- Dial and External Features
- The blue dial provides indications for hours, minutes, sweep seconds, and a framed date window at 3 o'clock. Markings on the dial include 'BWC SWISS' below the 12 o'clock position, and 'AUTOMATIC 25' over '200 METERS' above the 6 o'clock position. The German description notes 'ab Herst. 200m wasserd.' (manufacturer-rated to 200 meters water resistance), though this reflects historical specifications rather than a verified contemporary performance test.
- Identity and Case Construction
- Described by the auction house as a BWC self-winding wristwatch originating from Switzerland around 1970, the watch features a cushion-shaped stainless steel case measuring approximately 42 x 37 mm. Visual inspection shows a brushed finish across the top surface, hooded lugs, and an outer rotating bezel calibrated with 10-minute numeric indicators, minute hash marks, and a triangle marker at 12 o'clock. The cataloguer notes a screwed-down case back. The watch is mounted on an unbranded black leather strap fitted through the hooded lugs.
- Reported Movement and Verification Limits
- According to auction cataloguing, the watch contains an ETA calibre 2782 self-winding movement featuring a flat rim balance, flat hairspring, and Incabloc shock absorber. The movement itself is not depicted in the provided imagery, meaning its internal configuration and calibre stamp rely entirely on the seller's documentation. The dating of 'around 1970' is an estimate provided in the auction listing, as no specific serial number or production ledger is recorded in the source.

- Research required: Water resistance of 200 meters is an original specification on the dial and description, unverified for functional status
