Caliber 52
Details:
Hallmarks 800 + Pt. Rooster (CH) + Crescent and Crown + small punch. It is in perfect condition; even the screws have no scratches, no dents. The covers are rose-coated.
Caliber 52 was very likely built between about 1905 and 1910.
This fits very well with the typical production period of Caliber 52, manufactured from about 1893 to about 1931/1940.
Case number: 390998. The case number (390,998) lies in the range that typically corresponds to about 1907–1913.
Designation / Type
• Manufacturer: IWC Schaffhausen
• Caliber / Movement: Caliber 52 – a classic, large Lépine movement (open-face pocket watch) without a hunter case.
The crescent + crown + small hallmark + 800 confirm the silver alloy 0.800, which was common at the time for many export pocket watches (CH/DE market standard).
The watch received a revision in April 2026 at Boxberg, the IWC-licensed watchmaking company.
