Identity and Archival Provenance
This open-face pocket watch is catalogued by the auctioneer as Patek Philippe reference 651 and dated circa 1937. According to source details, the watch is accompanied by a Patek Philippe Extract from the Archives confirming a manufacture date of 1937 and a sale date of February 16, 1938. The auction condition report states that the dial, case, and movement are signed Patek Philippe. Internal movement and case serial numbers are not recorded in this source.
Reported Movement and Physical Condition
Cataloguing lists a manual movement running caliber 17'''25/12. The seller's condition report states the movement was in working order at the time of cataloging, but notes it was not tested for accuracy. Movement components are not visible in the provided lot image. The case is reported by the seller to have scratches and a few nicks, with the front and back showing evidence of being opened. The dial, hands, and hour markers have developed patina; the dial also has scratches, including two larger scratches near the outer edge between 8 and 9 o'clock and between 11 and 12 o'clock, alongside apparent corrosion to the outer edge.
