    The Vintage Handset. Broad Arrow. Old Radium.

    An iconic broad arrow handset in a mirror-polished silver finish, filled with 100% Swiss Super-LumiNova® Old Radium. The broad arrow shape has its roots in mid-century military and dive watches — it is blunt, legible, and serious. The Old Radium lume adds a period-correct warmth: a cream-tan face in daylight and a long-lasting green glow at night.

    For vintage-inspired builds where the goal is a coherent aesthetic across dial, lume, and hands. Pairs with LA Old Radium dials and Old Radium chapter rings for a fully tonal vintage system.

    Period-correct, modern quality.
    The broad arrow shape and Old Radium lume colour are a vintage specification. The Swiss Super-LumiNova® inside is ISO 9001 certified quality — not period compromise.

    Broad arrow shape.
    The blunt, unmistakable broad arrow profile — a mid-century tool-watch standard. Reads clearly under adverse conditions, which is exactly what it was designed for.

    Old Radium lume.
    100% Swiss Super-LumiNova® Old Radium — cream-tan in daylight, long-lasting green at night. The lume colour that defines the vintage aesthetic.

    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® Old Radium, for a long-lasting green glow at night, with a warm cream-tan tone in daylight. That aged look suits vintage and heritage builds, where the patina is the point.

    Outstanding lume!

    Old Radium style lume is commonly weak in the glow department. Especially for long duration over 8+ hours. These hands are excellent in long duration and luminosity. Five stars!

    Fast shipping and as described!

    Adriel was kind enough to write a handwritten thank-you card inside the packaging :)

    The hands for my project were packaged and shipped with care, and were exactly as described. Thank you!!

    Hi there,

    Do you have the broad arrow hands - old radium in black as well? I see an image of them in polished silver and black, and want to order them in black.

    Thanks!

    Hi Chris,

    Thanks for your interest in our Broad Arrow Hands!

    I’m sorry, but I do not currently offer these hands in black. Whatever options are available are already listed on the website.

    If you have any other questions or need assistance with your build, just let me know – I’d be happy to help!

    Best,
