Ginga (銀河) Tūrubi Seiryō (Special Edition) - Ltd Ed 50pcs

Five years was never a milestone we felt should be marked by something louder or more complicated. If anything, it invited us to reflect on why Hitori exists in the first place.

Every collection we have created has begun with the same question: does this deserve to exist? Every line, every case profile and every dial surface must earn its place, not because it follows trends or introduces novelty, but because it carries a story worth preserving. For us, watchmaking has always been an exercise in restraint, allowing culture, craft and personal experience to shape the object naturally.

Some projects spend years following a carefully planned roadmap. Others begin with a simple question. The Ginga Tūrubi belongs to the latter.

Hitori Ginga (銀河) Tūrubi Seiryō (Special Edition) - Ltd Ed 50pcs

Five Years in Motion

Mechanical watchmaking often sits at two extremes. There are honest, utilitarian watches built around value and reliability, and there are the grand expressions of haute horlogerie, where finishing and complexity often come with equally extraordinary prices. Between these two worlds, genuinely thoughtful watchmaking has become increasingly uncommon.

Since its founding, Hitori Watch Co., or ひとり, has quietly occupied its own space. Rather than pursuing trends or prestige, the brand has sought to express Japanese culture through contemporary watchmaking, pairing practical engineering with traditional craftsmanship.

From the Ryukyu Diver and Yoshino to the Meguro GMT and Nexus, every collection has drawn inspiration from a different place, season or cultural tradition across Japan. The Ginga Tūrubi marks a different chapter altogether.

For more than two centuries, the tourbillon has represented one of watchmaking's most celebrated mechanical achievements. It is often viewed as the pinnacle of technical craftsmanship, but that was never the reason for creating one.

The question was never whether Hitori could create a tourbillon. It was whether we could create one that still felt unmistakably like a Hitori.

The answer became the Ginga Tūrubi, or "Galaxy Tourbillon". Rather than using the complication as the centrepiece, the watch treats it as one element within a complete design. The integrated architecture, sculptural case and restrained proportions carry equal importance, resulting in a watch where engineering and design exist in quiet balance.

Hitori's first exploration in the world of tourbillon, Ginga Tūrubi 銀河

Built Upon What We Trust

Every project begins with a foundation. Ours was the Miyota 8 Series.

Long respected for its slim profile, dependable performance and straightforward serviceability, it provided the reliability we wanted before a single component was redesigned.

Building a flying tourbillon upon that foundation required almost every aspect of the regulating system to be reconsidered. Working together with our engineers and watchmakers in Nagano, the movement was extensively re-engineered. The rotating cage was supported by an entirely new structure, the gear train was redesigned to drive its one-minute rotation, the escapement received a dedicated mainplate, and power delivery was recalculated to ensure the movement retained the dependable character that first made the Miyota platform so highly regarded.

The challenge was never simply building a tourbillon.

It was building one that still behaved like a watch made to be worn every day.

Dial inspired by the gentle flow of Yanagawa's tranquil canals

Quiet Complexity

Just as important as the movement is the watch surrounding it.

The integrated bracelet style continues the faceted architecture of the case, echoing the overlapping geometry of traditional Japanese yoroi armour. Every surface transitions naturally between satin brushing and distortion-free mirror polishing, allowing light to define the form rather than decoration.

On the dial, applied stellar indices shimmer subtly as they catch the light, while the flying tourbillon rotates quietly beneath them, never dominating the composition. Despite the complexity within, the proportions remain balanced and comfortable on the wrist, allowing the watch to express itself through its finishing, architecture and careful restraint rather than sheer presence.

Producing the Ginga Tūrubi requires significantly more time than any previous Hitori project. Every movement demands careful adjustment, while each case and bracelet undergoes an extensive finishing process before final assembly in Japan.

For that reason, production is limited to just 50 pieces worldwide.

More than a celebration of five years, the Ginga Tūrubi represents where Hitori is heading next. It reflects the same belief that has guided every collection before it: that meaningful watchmaking is never about making more, but about making something worthy of lasting.

A Quiet Reflection

There is a quiet irony to the tourbillon.

As mechanical watchmaking has evolved over the past two centuries, the complication has become less essential than ever before. Modern movements have achieved levels of reliability and precision that Abraham-Louis Breguet could scarcely have imagined. Today, there are simpler and more effective ways of keeping accurate time.

Yet perhaps that is precisely why the tourbillon continues to endure.

For us, it has never been about pursuing the highest degree of precision. It is a reflection of something far more enduring. A reminder that the finest expressions of craftsmanship are rarely born from necessity alone, but from a desire to explore what human hands and minds are capable of creating.

The Ginga Tūrubi was never conceived as a statement of prestige, nor as an exercise in mechanical excess. We approached it as we have every Hitori before it, by asking whether it deserved to exist. Not because the world needed another tourbillon, but because we believed there was still room to interpret one through our own philosophy of restraint, balance and quiet design.

Every rotation of the cage serves as a reminder that watchmaking has always been about more than measuring time. It is about preserving knowledge, refining technique, and carrying forward generations of craftsmanship that continue to inspire those willing to devote themselves to the pursuit.

In a world increasingly defined by efficiency, the tourbillon remains wonderfully unnecessary. Perhaps that is exactly what gives it meaning. It reminds us that not everything of value must justify itself through practicality. Some things exist simply because they represent the very best of what we are capable of creating.

Faceted Sashi Yari hands continue this dialogue between tradition and contemporary craftsmanship

Japanese Armour, Reimagined

While the Ginga Tūrubi marks Hitori's first exploration into the world of tourbillons, it remains grounded in the same principles that have shaped every collection before it. Rather than allowing the movement to dictate the watch, Hitori began with the architecture itself.

The case and bracelet were conceived as a single composition, defined by sharp geometry, restrained proportions and a low profile that sits naturally on the wrist. Its inspiration comes loosely from kasane yoroi architecture, the layered armour once worn by samurai, translated into a modern form through overlapping planes and faceted surfaces instead of decorative motifs. There are also subtle echoes of the integrated sports watches that emerged from Japan during the late 1960s and 1970s, though the Ginga Tūrubi is less a revival than an interpretation. It is neither an extension of the Nexus nor a glimpse of every Hitori to come. Instead, it represents a moment of exploration.

The case measures 39 mm in diameter, 12.9 mm thick, with a compact 46.5 mm lug-to-lug distance. Crafted from 316L stainless steel and water resistant to 100 metres, its proportions were chosen to balance presence with everyday wearability. The integrated bracelet flows directly from the mid-case, creating a continuous silhouette that emphasises the architecture rather than individual components. More importantly, the watch was never designed to impress through specifications alone, but through the coherence of its design.

Viewed closely, the case reveals a disciplined approach to surface treatment. Its only pronounced curve runs along the case band, gradually transitioning into sharply faceted lugs before disappearing into the bracelet. The geometry remains crisp without becoming aggressive, giving the watch a distinct identity from every angle.

Conceived as a single composition, sharp geometry joins case and bracelet in quiet balance

Much of the exterior is finished with fine satin brushing, allowing the architecture to define the watch rather than reflections. Mirror polishing is reserved only for the narrow bevels, creating subtle shifts in light that reveal the complexity of the case as it moves. Every surface passes through Hitori's seven-stage hand-finishing process, carried out by experienced craftsmen in Japan. The diamond-cut crown sits neatly within the profile of the case, preserving both comfort and the uninterrupted flow of the design.

The bracelet follows the same philosophy. Its faceted links echo the layered construction of traditional Japanese armour, while alternating brushed and polished surfaces create depth without unnecessary ornamentation. Rather than functioning as a separate component, it completes the architecture of the watch.

Taken as a whole, the Ginga Tūrubi is more than a case designed to house a tourbillon. It is an exploration of proportion, geometry and craftsmanship, demonstrating that mechanical complexity need not come at the expense of restraint. Like every Hitori before it, the watch was shaped by a simple question that guided the project from the beginning:

What happens when a tourbillon is approached through our own lens?

"Wakare-michi no Hikari"

On the chapter ring, stellar indices shimmer subtly as they catch the light

Light at the Fork in the Water (分かれ道の光)

"The dial doesn't simply tell the time. It invites a closer look. As the light changes, new layers begin to emerge, revealing textures inspired by nature that are easy to miss at first glance. It is a dial that rewards familiarity rather than demanding attention."

The Ginga Tūrubi continues Hitori's belief that function and form should exist together. A flat sapphire crystal with an inner anti-reflective coating offers excellent clarity while allowing the dial to remain the natural focal point of the watch.

Its surface draws inspiration from the canals of Yanagawa in Fukuoka. Gentle undulations echo the movement of water flowing beneath willow trees and old stone bridges, creating a texture that constantly shifts with changing light. Finished in a clear blue known as Seiryō, the dial recalls the quiet rhythm of a donkobune drifting along the canals. It is neither glossy nor heavily textured, instead finding a balance between depth and subtlety.

Encircling the dial is a raised chapter ring finished with Hitori's signature satin brushing. Applied star indices are individually mounted onto the ring, recalling the distinctive "Galaxy" dials of the 1950s while taking on a character of their own. Alternating with Art Deco numerals at each cardinal point, the layout remains balanced and immediately legible. Every marker is filled with Super-LumiNova before being paired with a clean, unobtrusive minute track.

Every surface undergoes Hitori's seven-stage hand-finishing process, executed by master craftsmen in Japan

The faceted Sashi Yari hands continue the same attention to detail. Their profile takes inspiration from the leaf-shaped blades of traditional Japanese spears, with one surface mirror polished and the other satin finished. This contrast allows the hands to remain clearly defined as they move across the dial, maintaining excellent legibility regardless of the angle or lighting.

At six o'clock sits the heart of the watch. The aperture is proportioned simply, allowing the flying tourbillon to remain the natural centre of attention without overwhelming the rest of the dial.

Above it sits a slender satin-finished bridge. At first glance it appears to support the mechanism, but its purpose is different. The tourbillon itself is suspended from beneath by a single bearing, eliminating the need for an upper support. The bridge instead frames the opening, providing visual balance while preserving the illusion that the rotating cage is floating within the dial. It is a small detail, though one that reflects Hitori's approach to design, where every element exists for a considered reason rather than decoration alone.

The three-armed tourbillon cage is secured with heat-blued screws and carries the balance wheel at its centre. As the balance, escapement and cage complete one full rotation every minute, the mechanism performs the same task envisioned more than two centuries ago: averaging positional errors caused by gravity. Around it, the visible components are finished with the same care found throughout the movement, favouring precision over excess.

For Hitori, the tourbillon was never intended as an exercise in prestige. It became an opportunity to reinterpret one of watchmaking's most celebrated complications through a philosophy rooted in restraint, practicality and thoughtful design, making it both mechanically engaging and genuinely wearable.

Hitori Calibre HT01—a reimagined Miyota 8215 automatic movement

Precision Engineered Miyota Foundation with Tourbillon Artistry

Turn the watch over and the Ginga reveals something considerably removed from a conventional automatic movement. The screw-down caseback is fitted with a tinted sapphire window treated with anti-reflective coating, allowing the mechanics to reveal themselves without demanding too much attention. At its heart is the Hitori Calibre HT01, a heavily modified automatic calibre derived from the architecture of the Miyota 8215, one of Japan's long-established mechanical workhorses. In the Tūrubi, however, that familiar starting point has been extensively reworked around a one-minute flying tourbillon.

Rather than simply placing a complication onto an existing movement, the conventional regulating organ has been replaced by the flying tourbillon at six o'clock, with the escapement carried within its rotating cage and the surrounding architecture modified to accommodate its operation. Most notably, the HT01 does not retain the 21,600 bph frequency of the conventional 8215. Its escapement has been reworked with a modified pallet fork and escape wheel, together with a revised balance assembly, raising the frequency to 28,800 bph, or 4 Hz. The higher frequency places greater demands on the movement's available energy, resulting in a power reserve of approximately 40 hours. While the HT01 traces its foundation to the Miyota 82 Series, the resulting movement is quite different from the calibre from which it began. There is something fitting about this approach for Hitori. Instead of beginning with an exotic movement chosen for prestige, we wanted to explore how far one of Japan's most familiar and dependable mechanical architectures could be transformed.

The flying tourbillon completes one rotation every sixty seconds, continually carrying the escapement and regulating organ through different positions. Historically conceived to average out positional effects caused by gravity, it remains one of mechanical watchmaking's most fascinating mechanisms. Here, the flying construction removes the conventional upper bridge and supports the cage from beneath, leaving the mechanism almost suspended within the dial. There is certainly theatre in watching it move, but spectacle was never the sole intention. The tourbillon was considered as part of the Ginga's architecture from the beginning, allowing it to sit naturally within the dial while preserving the compact 39mm proportions and everyday character of the watch.

Flying tourbillon replacing the traditional regulating organ at 6 o'clock

That everyday character matters. The Ginga Tūrubi was never intended to become a delicate object destined to spend its life behind glass. Despite the mechanical complexity visible at six o'clock, the Calibre HT01 remains automatic, conceived to be wound by movement, placed on the wrist and lived with regularly. With approximately 40 hours of power reserve when fully wound, the complication changes what happens inside the watch without changing our belief that a mechanical watch ultimately earns its meaning through wear. It also opens the door for more collectors to experience the fascination of a flying tourbillon without necessarily treating it as something precious or distant.

Through the caseback, another distinctly Hitori element comes into view. The customised metallic winding rotor is decorated with a traditional Japanese wave motif, introducing texture and movement while remaining harmonious with the rest of the watch. Subtle variations in its metallic hues mean that no two rotors appear entirely identical. Inscribed upon it is a passage from Japanese poet and calligrapher Mitsuo Aida: 「人生において 最も大切な時 それはいつでも いまです」, meaning, "In life, the most important moment is always now."

Perhaps this is also where the tourbillon continues to hold its charm for collectors today. Its original purpose belongs to another period of watchmaking, yet there remains something compelling about seeing such a small mechanical construction constantly alive on the wrist. The cage turns once every sixty seconds, quietly and continuously, while Aida's words remain on the other side. We did not choose the mechanism simply because it is complicated, or because of the prestige a tourbillon has come to represent. We were drawn instead to the mechanical interest of watching the escapement rotate, and to the many small components working together to make that possible. Something mechanical, imperfect and alive, returning to the same place once every minute. Perhaps that is why people still collect tourbillons today. They are mechanically unnecessary, but therein lies much of their appeal: an elaborate solution to an old problem, preserved today simply because it remains fascinating to observe.

Geometry with Purpose — The Kozane Bracelet

The design language of the Nexus extends naturally beyond the case into the Kozane Bracelet, named after the kozane, the small overlapping scales that formed traditional Japanese yoroi armour. Like the case itself, the bracelet is shaped around the principle of layered construction, where each link overlaps the next with quiet precision. Rather than existing as a separate component, it flows seamlessly from the sculpted lugs, creating a continuous silhouette that appears carved from a single piece of steel. Every proportion, transition, and facet was carefully considered to balance crisp geometry with fluid articulation, allowing the bracelet to wear with remarkable comfort while remaining visually composed.

The finishing follows the same philosophy. Broad satin-brushed surfaces establish the bracelet's quiet character, while sharply defined mirror-polished bevels frame every edge, allowing light to travel naturally across each link as the wrist moves. It is a restrained expression of craftsmanship, one that reveals itself gradually rather than all at once. Nothing exists for decoration alone. Every surface, every chamfer, and every transition contributes to a bracelet that complements the watch instead of competing with it.

Kozane Bracelet: Layered links overlapping with quiet precision

As Hitori explains,

"We wanted to rethink what an integrated bracelet could be. One that flows naturally from the case, wears effortlessly throughout the day, and carries a quiet sense of presence. Inspired by the layered construction found in traditional Japanese craftsmanship, every detail serves a purpose. Our goal was never simply to attach a bracelet to a watch, but to create something that feels complete from every angle."

Measuring 20 mm at the lugs before tapering gracefully towards the clasp, the Kozane Bracelet sits close to the wrist with exceptional balance. Every individual link is meticulously finished using Hitori's signature combination of directional satin brushing and crisp mirror-polished bevels, echoing the sculptural language of the case while allowing the bracelet to articulate with surprising fluidity. Like the Nexus itself, it was designed not to demand attention, but to quietly reward those who appreciate thoughtful design and enduring craftsmanship.

Completing the Kozane Bracelet is a Musubi clasp developed specifically for the Tūrubi, designed to feel like a natural continuation of the bracelet rather than an afterthought. Its broad brushed surface and restrained proportions allow it to disappear into the overall design, while a concealed tool-free micro-adjustment mechanism provides everyday adaptability without interrupting its clean form. The subtle 「ひとり」 engraving serves as the only visible signature, reflecting Hitori's belief that the finest details are often those that reveal themselves only after years of ownership.

Beyond the Passing Seasons: A Milestone of Craft and Spirit

The Ginga Tūrubi is more than Hitori's first tourbillon. It represents a moment of growth for the brand—a willingness to explore unfamiliar territory while remaining grounded in the values that shaped its identity from the beginning.

Its layered dial continues to reflect the quiet movement of Yanagawa's canals, framed by faceted hour markers and the bamboo leaf-inspired Sashi Yari hands that have become a defining feature of Hitori's design language. Beneath them, the flying tourbillon introduces a gentle rhythm to the dial, while the re-engineered Miyota movement reflects the same balance between dependable engineering and thoughtful craftsmanship.

Limited to just fifty pieces, the Ginga Tūrubi was never conceived as an exercise in technical superiority. Nor was it designed to compete with the established world of haute horlogerie. Instead, it asks a quieter question: what happens when one of watchmaking's most celebrated complications is interpreted through the philosophy of Japanese monozukuri?

A versatile expression: The Tūrubi paired with its additional strap

Hitori shares this thought simply:

"Over the years, we've come to realise that time itself is the greatest teacher in watchmaking. Not only the time displayed on the dial, but the years spent refining an idea, living with it, and learning when to leave something untouched. A well-made watch is never rushed. It is shaped by patience, conviction and care. That rhythm belongs to monozukuri, not marketing."

Perhaps that is what makes the Ginga Tūrubi meaningful. It is not simply about owning a tourbillon, but about owning a chapter in Hitori's journey.

The finishing differs from the Yoshino and the architecture departs from the Nexus. Even the movement follows a different path. Yet every decision remains guided by the same belief that has shaped every Hitori watch—to create objects that are honest, enduring and a genuine pleasure to wear.

This is not a watch intended for everyone, nor was it ever meant to be. It is a limited exploration. A quiet milestone. A reflection of where Hitori stands today, and a glimpse of where it may quietly go tomorrow. Some watches celebrate achievement, but the Ginga Tūrubi celebrates curiosity.
