Hand-wound movement
18,000 vph, hacking seconds, 58-hour reserve measured on six positions.
Höcker & Sons is a family atelier producing 120 watches per year. Calibre 12 is a 38 mm field watch with a hand-wound movement we assemble across two benches, a double-domed sapphire crystal and a case designed so any watchmaker can open it with standard tools. We publish power reserve, amplitude targets and parts prices on this site. No dealer network, no waiting lists you cannot see. Höcker & Sons prints timing results from six positions inside the box and lists parts prices before you book service. Strap makers can download lug drawings without creating an account. Each watch ships with a printed timing card, strap change instructions and a parts price list dated the month of assembly. Service appointments include amplitude readings taken when the case is opened. We publish mainspring replacement intervals and document which components work with third-party service partners across Europe and North America. Lug widths, crystal height and hand lengths are dimensioned on the specs page so strap makers can fit without guesswork. Every case back shows serial, regulation date and the watchmaker who performed the final timing check before boxing. Service pricing lists labour separately from parts so you can compare quotes. Waiting lists show position and expected month publicly.
Five-year warranty. Service manual PDF is free.
