3D watch builder, prototype

An SKX-type diver assembled from real mod parts: each insert, crystal, dial, chapter ring, bezel and strap below is a product you can buy, modelled to the sizes its seller publishes, with a link to the product page. Where a seller publishes no size, the part says so. The case and the hands are generic for now. Drag to turn the watch; the top view is one button away.

Fits with a change

Each check compares published figures: the movement maker’s drawings, the sellers’ pages and our own design for the generic parts. A seller’s compatibility list is shown as a claim, not a measurement.

Checks

  1. Crown, stem and date windowNeeds a change

    The case puts the crown at 4 o’clock. The TMI NH36 stem points to 3 o’clock and runs through the pivot, so the movement turns 30° clockwise in the case, and the dial turns with it. The stock disc, which the maker lists for crown 3 o’clock / window 3 o’clock, then reads at 4 o’clock, but the window of SKX009 dial (Lucius) is at 3 o’clock. It needs a disc printed for a crown at 4 o’clock: a seller lists TMI NH36 for that crown (“NH36 Day-Date @ 4H Crown for a case with the crown at four”), which the maker's table does not.

    • Case crown: 120° (4 o’clock) (our design)[3]
    • SKX007 crown: 4 o’clock (measured)[4]
    • TMI NH36 stem: at 3 o’clock (maker)[5]

    • SKX009 dial (Lucius): day-date window (drawn by us, not published)[2]

  3. Dial feet and the movement’s foot holesFits

    Lucius Atelier makes SKX009 dial (Lucius) for a crown at 4 o’clock, as in this case, so its feet meet the holes of the turned TMI NH36 at 2:36 and 8:33.

    • TMI NH36 foot holes: 1:36 and 7:33 with the stem at 3 o’clock (maker)[8]
