The component collection

Cases and bracelets

A case is not machined for a calibre, it is machined for a footprint. That is the single idea this catalogue turns on, and it is why a GMT, a skeleton and a day-date can all drop into the same SKX: they are the same 27.4 mm disc at the same height. The footprint groups are listed at the bottom of the page.

Every picture here is rendered from the part's own record — the diameter, lug-to-lug, thickness, lug width, bezel, crown position and caseback in the tables below are the ones drawn. Click a part for every angle: a case from three-quarter, the dial side, the crown side, across the lugs, from behind and from the back; a band closed round a wrist, from straight above where you can see its taper, at its end link and at its clasp.

Cases

Seats up to is the widest movement the seat takes by the tallest the caseback will close over. Dial is the largest dial the opening clears. Get either wrong and the parts arrive and do not go together.

Bracelets and straps

Two things decide fitment and only two: the lug width, and the end. A curved solid end link is machined to one case and fits nothing else — an SKX end link will not sit on an SRPD, although both are 22 mm. Anything marked straight goes on any case of the right width, at the cost of a small gap against curved lugs.

The footprint groups

Each group is one disc of one diameter at one height, taking one size of dial and one set of hand holes. Everything in a group is interchangeable in a case cut for that group, which is what makes a catalogue of parts possible at all.
