The Sport Handset. Nautilus Profile. Polished Black.

The Nautilus hand is a sport profile with more body than a baton or pencil — wide enough to carry the dial's weight on its own, refined enough to sit cleanly on a dress-adjacent build. In polished black, it works as a graphic element: high contrast against light dials, tonal and controlled against dark ones.

Filled with 100% Swiss Super-LumiNova® BGW9 Grade A. The lume loads the full hand body, not just a pip — blue glow for up to 8 hours from a full charge, consistently across the H/M hands.

Black hands, blue glow.
The polished black Nautilus is the sport handset for builds where contrast and legibility are the brief.

Nautilus profile, polished black.
A rounded, substantial sport shape in a glossy polished black finish. Works as a graphic contrast element on pale dials, or as a tonal choice on black and navy builds where the lume does the legibility work.

BGW9 Grade A — full-body lume fill.
100% Swiss Super-LumiNova® BGW9 Grade A loaded across the full hand body. Blue glow for up to 8 hours — the same top-grade lume across the Nautilus range for consistent legibility at night.

Will these hands fit my movement?

Check the Fit Movements list in the Specs tab against your caliber. The handset fits a wide range of Seiko movements — including 7S, 4R, 6R, NE and NH families — because they share a common pinion pattern. If your caliber is on the list, these hands fit.

What are the pinion sizes?

Hour 1.50mm, minute 0.88mm, second 0.198mm. The pinion is the hole at the base of each hand that presses onto the movement — these dimensions match the standard Seiko pinion pattern shared across the calibers in the fit list.

Can I use these on a GMT (NH34) build?

The hour, minute and second hands fit the NH34. A GMT build also needs a separate GMT hand, which is not included in this set.

Do the hands come with lume?

Yes — these hands are filled with 100% Swiss Super-LumiNova® BGW9 Grade A, for a long-lasting blue glow at night, with a clean metal finish for daytime wear.
