Marine Master Hands - BGW9 - Polished Silver

The Sport Handset. Marine Master Profile. BGW9 Swiss Lume.

The Marine Master handset — MM for short — is built for legibility and presence. The bold, solid profile commands a dial without fuss: mirror-polished on top, with angled edges that catch light and define each hand's position clearly across any dial colour.

Filled with 100% Swiss Super-LumiNova® BGW9 Grade A — the cool blue charge that holds through the night. The lume sits in the hand body, not as a pip or dot, so charge and readout are consistent from any angle.

Bold hands read bold dials.
The MM profile suits sport builds, diver dials, and any watch where legibility comes before decoration.

Mirror-polished top, angled edges.
The polished flat top reflects a clean line of light. The angled sides create definition even at low viewing angles — the combination that makes the MM profile as legible at a glance as it is on a watch photography shot.

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 after charge. The ice-blue that has become the benchmark for sports watch lume.

Questions, Answered

Everything worth knowing before you build.

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.
