The Fathom Handset. Vintage-Diver Character. Designed for the Great Fathom Dial.

A polished-silver handset with vintage-diver character — clean shapes and honest proportions that read instantly, the way a dive watch should.

These were designed alongside The Great Fathom Dial — the original pairing — and carry 100% Swiss Super-LumiNova® BGW9, Grade A being the highest-grade BGW9 on the market, for a long-lasting blue glow.

Lume pairs perfectly with our BGW9 parts.
On the Great Fathom dial — or any BGW9-lumed face — hands and markers glow as one design.

Designed for the Great Fathom.
Drawn up alongside The Great Fathom Dial, so proportions, lume tone and character land as one design rather than an assembly.

Swiss BGW9 glow.
100% Swiss Super-LumiNova® BGW9 keeps the vintage-diver face legible deep into the night.

Heads up — hands are one part of the 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.
