Design & Craftsmanship

The "Hebitama" SNXS Heritage Reimagined

Drawing from the beloved 1970s SNXS series, this 32.00 mm reference preserves the signature "Hebitama" silhouette—a flowing case curvature celebrated by vintage Seiko collectors for its organic, rounded profile. Scaled to tailored 32 mm dimensions with a lug-to-lug distance of 38.7 mm, the case features a lowered center of gravity that rests flush against feminine and slender wrists while protecting the recessed crown at the 4 o'clock position.

Sunray Blue Depth & Silver Contrast

The dial captures shifting ambient lighting with a fine radial sunburst finish, moving across hues of vibrant royal blue to deep oceanic navy. Polished, bevelled silver-toned baton indices and matching Dauphine-style hands provide sharp legibility, accented by an orange-tipped seconds hand reminiscent of vintage 1970s Seiko 5 sports models and a cleanly framed day-date display at 3 o'clock.

In-House Mechanical Engineering: Calibre 2R06

Beneath the solid screw-down case back beats the in-house Seiko Calibre 2R06 automatic movement. Designed specifically for smaller case architectures without compromising chronometric reliability, this 21-jewel calibre provides approximately 40 hours of power reserve. Unlike traditional entry-level automatics, it includes both manual winding via the crown and a hacking seconds mechanism for accurate synchronization.
