Waldenburg Silver Watch, Engine-Turned Case, c.1908

Revue Thommen has been making movements in Waldenburg, Switzerland since 1853, and this solid open-face example shows exactly why they built their reputation. The movement is almost certainly the Calibre 30 - a split three-quarter plate gilt brass movement running at 18,000 beats per hour with a 32-hour power reserve and 15 jewels. The case is 0.900 silver - the Continental standard - bearing the German Halbmond und Reichskrone guarantee marks, which tells us this watch entered the German market before reaching its first owner. The engine-turned guilloche pattern covers the back entirely, with a blank cartouche at centre.

At 49mm it sits well in the hand. The white enamel dial is in excellent shape: clean Arabic numerals, a subsidiary seconds register at six o'clock, and a pair of blue steel hands. No chips, no hairlines. The movement winds smoothly, sets cleanly and runs. The silver case has honest age wear consistent with over a century of life - surface patina and light marks on the inner dome - but no dents or damage worth noting.

A reliable, well-made Swiss pocket watch from a named maker, with a documented history and a German market provenance.
