    The Great Oak Hands - Polished Silver

    $59 SGD
    Swiss Lume

    The Oak Handset. A Motif in Every Hand. Polished Silver.

    The oak handset carries its namesake design across the whole set — and without sparing any details, the second hand wears the oak motif too. Polished silver, distinctive without shouting.

    Each hand is filled with 100% Swiss Super-LumiNova® BGW9 Grade A — the highest-grade BGW9 on the market — for a long-lasting blue glow.

    Lume pairs perfectly with our BGW9 parts.
    Pair with a BGW9-lumed dial and the oak motif keeps its presence around the clock.

    Oak motif, all three hands.
    Most handsets give the second hand a plain profile. Here the oak design runs through hour, minute and second — the detail you notice on the third look and never unsee.

    BGW9 Grade A lume.
    The highest-grade BGW9 on the market, charging fast and glowing blue long into the night.

    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.
