Seiko 5 Sports “Field Street Style” GMT Blackout Ref. SBSC013

Since its establishment in 1968, the Seiko 5 Sports collection of mechanical watches has embodied durability and precision. The collection, revitalized in 2019, injected a youthful vibrancy into its decades-old legacy. In 2022, Seiko introduced a groundbreaking addition—a new GMT series based on the proven Caliber 4R platform, known for its reliability. This bold move marked the birth of the Seiko 5 Sports GMT Series, enriching the collection with the convenience of international timekeeping.

Anticipating the integration of the GMT movement into other models, we're thrilled to unveil the Seiko 5 Sports Style Field GMT series. In this series, Seiko masterfully blends functionality, specifications, and affordability. Gnomon Watches proudly presents the SBSC013 model featuring a full black steel case, dial, and bezel. The PVD black stainless steel "field" case, with reduced dimensions compared to its counterparts, measures 39.4mm in width, 13.6mm in thickness, and 47.9mm lug-to-lug.

The case boasts multi-finished polishings, including the lugs and the fixed bezel, creating a rugged tool watch aesthetic. Complementing this is the fixed black bezel insert adorned with 24-hour markings. The push-pull crown, maintaining the 2019 Seiko 5 design, ensures a water resistance of 100m. Flipping it over, the screw-down case back with a glass display allows enthusiasts to admire the intricate mechanical components. The domed Hardlex crystal enhances legibility, contributing to a high-contrast and seamless reading experience.

4R34 automatic caliber

The full black dial version features a bright orange GMT hand for added visibility. Even in low light conditions, Lumibrite-coated hands, indexes, and GMT hand ensure effortless timekeeping. The military-inspired design includes a 24-hour inner marking, bold Arabic hour markers, and a functional date display at 3 o'clock, framed in metal, with the GMT text positioned beneath the Automatic script.

A rugged calfskin NATO strap adorns this GMT timepiece. The NATO comes with matching black buckle and keepers, allowing one to get a seamless full black aesthetic on the wrist. The heart of the watch houses the newly-crafted 4R34 movement, an evolution of the Caliber 4R platform, introducing a fourth hand—the GMT hand. This movement allows hacking and manual winding, featuring both a date and an independently adjustable 24-hour hand.
