    Nautilus II Hands - Polished Black

    $59 SGD
    Swiss Lume

    The Sport Handset. Nautilus II Profile. Polished Black.

    The Nautilus II is a redesigned sport hand — an updated profile that sits more confidently on modern dial layouts. A slightly taller hour hand at 9mm (versus 8.5mm on the original Nautilus) gives the build more visual weight, while the polished black finish adds the graphic contrast that makes a sport watch read at a glance.

    Filled with 100% Swiss Super-LumiNova® BGW9 Grade A for consistent full-body charge and blue night glow. The proportions read as contemporary; the lume ensures legibility when it counts.

    The modern sport hand.
    Updated proportions, polished black finish, top-grade BGW9 lume — the Nautilus II is the sport handset for builds that should look current.

    Nautilus II — updated proportions, polished black.
    Slightly taller hour hand (9mm) than the original Nautilus, giving the set more visual presence on the dial. Polished black finish for high contrast against light dials and graphic legibility against dark ones.

    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 lume performance that makes a sport build complete.

    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.
