I recently acquired a Vacheron Geneve trench watch from circa 1900-1915 — a silver pocket watch case converted to wristwatch with soldered wire lugs. The caseback inscription reads “Cylindre 10 rubis / Vacheron / Geneve” and the movement appears to be an original Swiss cylinder escapement in good condition based on visual inspection (photos attached).

The watch needs a full service. The movement is dry and dirty but visibly intact — the cylinder itself appears undamaged. I’m not expecting any heroics, just a proper clean, oil, and regulation by someone who actually knows cylinder escapements.

Can anyone recommend a watchmaker who specifically works on Swiss cylinder escapements from this era?

Thanks!
