Nexus Hanaasagi 花浅葱

“What sets Hitori apart is a quiet sense of solitude and freedom. An independence not just in how the watches are made, but in the way they think about time and design. Each piece reflects a deep connection to culture, not in a surface-level way, but as something lived and felt. It’s not just about looking back or romanticizing the past; it’s about carrying forward a certain spirit—a belief in craft, in storytelling, and in doing things with purpose.”

Hitori Nexus Hanaasagi 花浅葱

In the world of mechanical watchmaking, there exists a nebulous stratum of design and pricing—often split between pragmatic affordability and high-end excess. On one end, we see robust, utilitarian pieces with impressive execution for their price. On the other, the horological powerhouses deliver extravagantly finished watches at equally extravagant prices. But in between, where refinement meets daily practicality, few brands succeed in delivering something truly uncompromising—let alone at an accessible price.

Known for its distinct blend of traditional and modern craftsmanship with an oriental East-Asian design, Hitori (or ひとり) continues to uphold its quiet philosophy of "One quiet vision. One enduring craft." This guiding belief has shaped the brand since its inception, offering collectors an immediate sense of the Hitori ethos. Hitori Watch Co. sets out to be an independent brand that delivers unique timepieces—painstakingly well-executed mechanical watches offered at an eminently excellent price point. Driven by the influence of Japanese culture and its traditional modus operandi, the philosophy displayed by this indie brand prioritizes value proposition, which is notably evident in both the mechanical and aesthetic sides of every piece. Through this commitment, Hitori consistently builds a unique and meaningful experience for its community.

From the Ryukyu Diver to the Meguro GMT, each of Hitori’s five collections draws from distinct facets of Japanese culture—seasonal motifs, geographical heritage, and even cross-cultural collaborations. Now, on the occasion of its fifth anniversary, Hitori introduces its sixth chapter: the Nexus collection. A culmination of its design journey so far, Nexus speaks not only to refined watchmaking but to a quietly ambitious philosophy that continues to resonate with a growing community of discerning collectors.

The inspiration Of The new Nexus Series


Tucked away in the suburbs of Fukuoka, Nexus World remains one of Japan’s most underrated architectural pilgrimages. Conceived during the height of Japan’s economic bubble, the project was masterplanned by Arata Isozaki and brought together a cohort of global architects—including a young Rem Koolhaas—to each design their own cluster of apartment blocks within a shared urban framework. Koolhaas’s contribution is one of the early works that prefigured his later fame—an experimental study in communal space, circulation, and façade modulation. His building stands as an open-air archive of early 1990s architectural thought, capturing the tectonic shifts of postmodernism, deconstructivism, and contextualism at a moment of intense cross-cultural exchange. The result is a quietly radical composition: buildings that range from poetic to surreal, bound together not by uniformity but by the conviction of experimentation.

Though the project never ignited a wider trend, Nexus World endures as a compelling detour for those who seek architecture off the beaten path.

Now, five years on the all-new Nexus collection builds upon past expressions, advancing Hitori’s design language by merging nature with architectural clarity. Inspired by Koolhaas’s vision of Japanese architecture in the early ’90s, the watch captures that same spirit of spatial experimentation—now distilled into a wristwatch form. The dial pays homage to the tranquil canals of Yanagawa in Fukuoka, its flowing textures echoing water in motion, grounding the piece in quiet beauty. Encased in a slim, sculptural two-piece case, the Nexus Hanaasagi embodies a refined minimalism—distinctly Japanese, deeply serene. More than a timepiece, it’s a wearable study in cultural nuance and crafted intention.

Hitori’s Modular Nexus Form

Named Hanaasagi (Flower Asagi / 花浅葱 in Japanese), the watch is presented in a 316L stainless steel case that measures 39.5mm across, 10.6mm in height including the box-shaped sapphire crystal, and 47.8mm from lug to lug. The proportions are remarkable, delivering a slim and ergonomic profile that retains notable wrist presence. Despite its refinement, the case is rated to 100 metres of water resistance, underscoring the careful calibration of design, engineering, and utility to ensure a balanced fit across a wide range of wrist sizes.

What distinguishes the Nexus is not only its dimensions but the architecture of the case itself. Conceived as an entirely new direction for Hitori, the two-piece modular case was inspired by Rem Koolhaas’s apartment block at Nexus World in Fukuoka. Development spanned more than a year, culminating in a design that wears thin yet communicates architectural strength. From every angle, the case reveals sharp transitions, layered forms, and a rhythm of surfaces that lend the watch a sculptural presence.

Hitori explains: “The design adds depth from every viewpoint. It reveals new details each time, engaging the eye and inviting the wearer to rediscover the watch continuously.”

The case construction embodies this philosophy. The lugs are built as separable components, a choice that improves finishing precision while creating new opportunities in design, durability, and long-term serviceability. An internal L-clamp system secures the lugs to the mid-case. Once locked by the screw-down case back, the clamp unifies the structure, ensuring rigidity and consistent water resistance. The system provides reliability whether worn daily, in the pool, or in open water.

The modularity enhances both aesthetics and function. Separated lugs allow sharper demarcation between polished and satin surfaces, while also enabling tighter tolerance control during assembly. Structurally, the design increases shock absorption and reinforces stress-bearing areas without compromising comfort. In the rare instance of damage, lugs can be replaced independently, extending the lifespan of the watch. The same system also anticipates future variants, allowing new materials, different lug geometries, or more aggressive profiles without redesigning the entire case.

Visually, the case balances modernist geometry with ergonomic flow. Downward curving lugs follow the natural line of the wrist, while sculptural slots and a recessed groove beneath the bezel create layered depth. Four distinct cutouts echo the exterior of Koolhaas’s Nexus, a subtle reference that shifts the watch from a mere instrument of time to a wearable sculpture.

The crown, called Tokudai Daiya for its oversized diamond-cut grooves, provides both tactile assurance and visual weight. The detachable case structure also grants access to surfaces often left unfinished. Distortion-free polished planes contrast with sharply brushed sections, while even the inner lugs and underside of the mid-case are completed to the same standard. More than seven distinct stages of polishing are undertaken, all executed by hand by veteran craftsmen.

The result is not simply a watch case, but a platform. It achieves durability, modularity, and sculptural refinement in equal measure. Where most watchmaking separates practicality from refinement, the Nexus demonstrates that both can coexist. The Hanaasagi edition embodies this equilibrium, a study in architecture, movement, and Japanese sensibility—designed for collectors who appreciate restraint and thoughtful craft over excess.

Reflections of Yanagawa, the “Venice of Kyushu”

“While contemporary independent watchmaking often celebrates bold experimentation, few manage to shape their ideas with the quiet intensity and sculptural depth that define true mastery. We continue to pursue this rare balance—where mechanical excellence meets thoughtful design, and every surface reveals intention. Like the spirit behind Hitori, it isn’t just about pushing boundaries, but about crafting meaning through form, finishing, and feeling.” -Hitori

The Nexus design continues Hitori’s focus on turning functional elements into something quietly expressive. To improve legibility, a flat sapphire crystal is fitted with inner anti-reflective coating, making it easy to read the time at a glance. Underneath, the brand’s nature-inspired philosophy comes through clearly in the dial.

The bokashi (fumé) dial is the centrepiece. Its surface takes after the calm waters of the Yanagawa Canals in Fukuoka, the same prefecture that inspired the case profile. The texture flows with quiet rhythm, echoing the slow drift of a donkobune as it passes by old wooden buildings. Finished with a soft satin sheen, the dial shifts gently under light. Its gradient turquoise tone references hanaasagi, a traditional Japanese colour—a blend of floral tones layered over asagi, a blue-green used historically in textiles. The result is subtle, rooted in craft and regional heritage. As with most things at Hitori, it’s a design that rewards time and attention.

The details reveal themselves gradually, starting with the applied hour markers. First seen in the Somei Yoshino collection, each faceted block has since been refined—now sharper, more deliberate— a testament to Hitori’s quiet mastery in quality and refinement.

These crisp, high-precision indices that reflect light with striking clarity, subtly and in shifting ways. Mirror-polished on the inner faces and sidewalls, each marker contrasts with the soft satin finishing on the remaining surfaces. The result is dynamic: when the polished planes darken, the brushed facets light up with rainbow-like hues —ensuring the dial is never flat, but always alive.

This interplay continues onto the bold “Sashi Yari” hands. Inspired by the bamboo leaf-shaped blades of traditional Japan, the faceted hands carry a quiet tension in their symmetry and taper. Each is finished by hands with contrasting surfaces—mirror on one half, matte on the other—yielding a distortion-free legibility wrapped in minimalist elegance. Cutouts at the tips or tails add both lightness and intention, allowing the hands to move in concert with the dial, perfectly aligned with each marker in quiet precision.

The polished metal frame around the date window at 3 o’clock is paired with a shortened hour marker to maintain visual balance. It’s a quiet detail, but one that reflects Hitori’s careful approach to design. Each hand is sized just right, moving in line with the markers and minute track. Nothing feels out of place. The result is a clear, steady reading of time—simple, deliberate, and calm.

The textured dial is anchored by the applied “Hitori” logo at 12, balanced by the blue “NEXUS // AUTOMATIC” text at 6. As a whole, the Nexus design explores space, light, and their quiet interaction with the natural world. It’s an approach that reflects Hitori’s broader philosophy—where form, function, and feeling come together in quiet harmony.

The Quiet Heart Within, Powered by a True Japanese Movement

Turn the watch over, and the Nexus offers more than just specs. The screw-down case-back features a custom sapphire crystal, tinted with a subtle pinkish-red AR coating—a small detail, but one that gives the watch a bit of quiet character. Through it, you’ll see the heart of the watch: the Japanese-made Miyota 9015, a slimmer, premium automatic movement that’s gained a strong following among enthusiasts for its reliability and performance.

Built entirely in Japan at Miyota’s modern facilities, this 11.5-ligne movement allows for a more refined case profile, while offering specs that easily rival Swiss equivalents. It runs at 28,800 beats per hour (4Hz), with 24 jewels, and supports manual winding, hacking seconds, and quickset date—all operated via the screw-down crown at 3 o’clock. Fully wound, it delivers a 41-hour power reserve, which is more than enough for daily wear.

What stands out visually is the open-worked winding rotor. Hitori custom-crafted it in steel, finishing it with their Japanese logo and giving each rotor a slightly different tone—so no two look exactly alike. It’s a small but thoughtful gesture, adding a layer of individuality to every piece.

On every rotor, you’ll also find a short engraved phrase: 「流れるままに」 (nagareru mama ni), which means “as it flows.” It’s a quiet, poetic line—a nod to taking things as they come, living in the present. Like the watch itself, it’s not flashy, but it carries a certain calm that stays with you.

Introducing the Karumo Bracelet

Each Nexus comes fitted with a 20mm multi link bracelet inspired by Karuta gote, the tile like armored sleeves worn by samurai in the late Muromachi period. The bracelet is called Karumo, a coined term blending Karuta with Mō (盂), carrying the sense of movement and flow. While its form references protection, it wears with a softness that feels almost organic. The structure is architectural in profile, yet it moves with ease, balancing tradition with modern restraint.

The engraved bracelet tapers to 18mm with precision, leading to a clasp embossed with “ひとり.” The clasp is not an afterthought but a deliberate detail, reworked entirely to complement the Karumo. Its compact construction was designed to match the bracelet’s refined silhouette while providing a secure hold. Each petite screw down link allows exact sizing on any wrist, removing the need for a micro adjust extension slider. Together, the bracelet and clasp stand as a complete system, designed from the ground up with the same discipline and attention that defines the watch itself.

Hitori describes the intent directly: “The idea was to redefine what a proper bracelet should be. Comfortable on the wrist, elegant without being loud. It draws from the traditional culture we have long admired, a quiet influence that continues to shape our work. The aim was to create something versatile and functional, yet refined enough to sit naturally with any watch it accompanies.”

The Karumo bracelet reflects this vision with careful execution. Each link measures 2.6mm in thickness and 6.3mm in length, shaped with precise slopes that accentuate the middle links. The surfaces are mirror polished with integrated finishing techniques, then joined with specially designed end links that introduce negative space into the structure. It does not demand attention but reveals its complexity when worn. The screwed links receive the same finishing treatment as the case, giving the bracelet a presence that feels substantial yet never heavy.

Handling the bracelet underscores its refinement. The clasp engages with a clean, precise action, making the process of fastening and releasing intuitive. On the wrist, Karumo wears with a balance of solidity and fluid motion. Like the armor that inspired it, the bracelet offers strength and assurance while remaining comfortable, a design that embodies restraint and quiet sophistication.

Specially created for Hitori, the Nexus arrives with an additional  vintage calf strap crafted in Augsburg, Germany. Each 20mm band is  handmade with vintage double-stitch detailing, and thanks to its  untreated finish, it will develop a rich patina as it ages naturally on  the wrist.

Where Japanese Craft Meets Architectural Intention

For its fifth anniversary, Hitori Watch Co. presents the Nexus Shirakawa —a watch that bridges the brand’s dedication to refined Japanese craftsmanship with a bold new architectural direction. Drawing inspiration from Rem Koolhaas’s early work in Fukuoka’s Nexus World, the Shirakawa introduces a completely reimagined case construction—modular, sculptural, and deeply thought-out. Its two-piece form reveals fluid lines and layered geometry that evoke a built structure rather than a traditional case. Every element, from the river-flowing textured dial to the oversized diamond-cut crown, speaks to Hitori’s growing ambition to combine form and symbolism. It wears slim but leaves a strong impression, offering sharp details and subtle finishing that rival watches well above its price point.

“As we enter our fifth year, we’ve chosen to mark it not with noise, but with intention. The introduction of our Nexus series isn’t about making a statement — it’s a natural step forward in our journey of watchmaking. The case and movement have both been built with care, reflecting the same principles that have guided us from the start: attention to detail, respect for tradition, and a belief that good things take time. What comes next will grow from this foundation — not rushed, but shaped steadily, as we continue to build a watchmaking voice that is distinctly our own.” - Hitori

Just as impressive is the dial, textured to evoke the gentle rhythm of Yanagawa’s spring canals. The turquoise surface shifts gently with the light, framed by faceted markers and leaf-shaped “Sashi Yari” hands that echo the case’s angular rhythm. Inside beats the reliable Miyota 9015, visible through a pink-tinted display back, paired with a custom open rotor engraved with the phrase 「流れるままに」—“as it flows.” It’s a fitting expression for a piece that captures time not just in seconds and minutes, but in thought, tone, and texture. For collectors seeking something outside the obvious lanes of Swiss or mainstream Japanese fare, the Nexus Hanaasagi quietly makes its case.
