Case and Reported Markings
The steel case is reported by the auction catalogue to measure approximately 34 mm in diameter and to feature a screw-down case back. The lot title dates the watch to around 1940 and associates it with the Second World War. The auction description states that the screw-down case back carries a U.S. Army military marking along with 'No. 3190'. However, the case back is not depicted in the provided photograph, so the specific layout, wording, and execution of these markings are not recorded in this visual record.
Dial and Visual Appearance
The watch features a silvered dial with luminous Arabic numerals and an outer railway minute track that includes five-minute Arabic markers. Time is shown with skeletonized blued-steel hands and a sweep center seconds hand. Below the 12 o'clock position, the dial is signed 'WATERPROOF HELVETIA'. Along the bottom rim at 6 o'clock, a small 'SWISS MADE' inscription is printed. The watch is fitted with an olive-drab woven textile pass-through strap with steel rings, described in the auction text as a military textile strap.
Movement and Condition Notes
The auction house identifies the internal mechanism as a Helvetia calibre 820B with center seconds. The cataloguer also reports the piece to be in very good condition and in working order. Because the movement and interior are not visible in the listing image, mechanical details such as finishing, jewel count, shock resistance, and factory stamps are not recorded in the available source data.
