Signed “Patek Philippe Genève” and marked “Swiss” at 6 o’clock. - Manual-winding mechanical movement. Bridges decorated with Côtes de Genève. Signed “Patek Philippe & Co – Geneve – Swiss”. Movement number engraved on the bridge: 999630. - Flexible 18k yellow gold band with polished and satin-finished links imitating a textured woven fabric. Ratchet clasp with a gold safety chain. Case dimensions: 15 x 15 mm Gross weight: 66.7 g Condition: In good overall condition. The movement is clean, showing no major signs of oxidation. One raised link on the bracelet is worth noting. Slight traces of oxidation on the dial. A routine service is recommended; the watch was in working order at the time of valuation.
