THE BENCH

There is one bench in this workshop. It stands where the kitchen of Haus Färberstraße 9 used to be, two streets below the Glashütte church, and it has held every movement finished here since 2011. The lamp is a fifty-year-old Waldmann with a new bulb. The tweezers are Dumont No. 3, dressed every Monday morning before anything else is touched.

Kaliber 72 is assembled twice. The first assembly is for truth — every wheel run in, every pivot burnished, the escapement matched and adjusted until the trace goes quiet. Then the movement comes apart completely. Every steel part is blued over a spirit flame, every plate takes its final grain, and it is assembled again — this time for good.

Between first and final assembly lie some three hundred and forty hours. None of them are interesting to watch. All of them are in the watch.

  • DI 04:12 — amplitude 301° dial-up, 296° crown left
  • beat error 0.0 ms after third truing of the roller
  • barrel-bridge screw No. 11 blued twice — first ran to plum
  • swan-neck tensioned; rate −0.8 s/d. leave it.

TWELVE A YEAR

Kaliber 72 is made in a series without end but not without patience: twelve movements a year, numbered from No. 001 in the order the letters arrive. The movement is finished, cased, regulated and rated here — no part of it is sent out, and no year’s twelve are alike in their engraving.

Delivery is quoted honestly: fourteen months from the day an order is confirmed, and only what can be finished is confirmed. Orders are taken by correspondence. A letter tells more than a form ever will.
