This is the second Hamilton 921 pocket watch conversion we have made available for purchase, our first one has been sold. This watch doesn't need a lot of words, its raw beauty and performance speaks for itself. ClockSavant provided design input into this watch in collaboration with a very talented and dedicated outside watchmaker who performed all of the work in sourcing, servicing, and manufacturing the watch. This is a true one-of-a-kind design. The vintage movement is a made-in-the-USA Hamilton Calibre 921 vintage pocket watch manufactured in 1947. This was one of Hamilton s finest movements. The movement was removed from a pocket watch, completely disassembled and serviced by the outside watchmaker working with ClockSavant, and then custom fit and assembled into the new modern case. We fitted a high quality deployant which was finished to match the case of the watch. If anyone ever asks you about the quality of made in the USA watches, you can show them the Hamilton 921 movement through the exhibition case back and their eyes will likely glaze over with admiration. We made great watches in the USA and it s a shame we don t make them any more. There are fledgling watchmakers working to recreate our history, and at ClockSavant we work to do our part by keeping horology and watchmaking alive with innovation, passion, and excellence in the USA. This is a large 42mm watch, if you like larger watches you will it very much. It has a pilot aviator inspired design with a unique satin sandblasted finish. The front and back crystals are made of sapphire with antireflective coating.

Size guide for wristbands

1 | Lug width

The lug width is the width of the strap at the end that is attached to the watch. This is the interior distance between the two lugs (horn-like protrusions) on the watch casing. The strap will fit your watch only if the lug width of the watch is the same width as the strap.

2 | Buckle width

The buckle width is the width of the strap at the buckle end. If you want to keep your watch’s original buckle and replace only the strap, the width of the original buckle must be identical to the strap width. For watches with folding clasps, please choose a strap specially made for your particular clasp.

3 | Strap length

The strap length is the combined length of the short strap side 3A (without buckle) and the long strap side 3B. For metal straps, the length of the strap including the clasp is measured in the closed position.

4 | Strap thickness

Strap thickness is the height of the strap. Many leather straps thin out towards the buckle end, or “taper”. If you want to keep your watch’s original buckle and replace only the strap, the strap thickness must match the height of the original buckle. For watches with folding clasps, please choose a strap specially made for your particular clasp.
