AI-assisted summary
Description from the seller
IWC Schaffhausen – KM Observation Watch – Caliber 67 – circa 1942 – in running condition
Historic pocket watch from International Watch Co., Schaffhausen, with a mechanical hand-wound movement, Caliber 67, and small seconds at 6 o’clock.
The bright, cream-colored patinated dial features black Arabic numerals, a minute track around the edge, and the inscription “International Watch Co. Schaffhausen.” Above it is the designation “KM,” as used on observation watches for the German Navy. The blue-tinted hands form a nice contrast to the dial.
Historical classification:
The case number 1,075,117 falls within the documented range of a series of IWC observation watches delivered to the Kriegsmarine via Gerl & Schipper in Cologne between July and December 1942.
The dating to 1942 is based on this serial range. An individual archival extract is not on file. A attribution to a specific ship or former owner is not known.
Movement and markings:
Inside there is the IWC hand-wound movement Caliber 67 with fine regulation. It bears the designation “C. 67,” the movement number 1,031,035, and the IWC seal “Probus Scafusia.”
The inner side of the case back features a circular decorative grind and is marked with the number 1,075,117.
