Rotary ladies wristwatch, manual wind movement stamped 21 Jewels with Incabloc shock protection, marked Swiss on the movement plate. Dial reads ROTARY with the winged logo, 21 Jewels, Incabloc, Swiss Made. Case back is stamped Stainless Steel, SD Empire. Case measures approximately 24mm excluding crown. No serial or date code is present on the case or movement, so the decade above is based on styling and comparable Rotary Incabloc models rather than a specific date stamp. Fitted with a worn leather strap showing cracking and wear from age. This watch is running as of the time of listing. Service is required for accurate timekeeping, and extended runtime without service is not guaranteed.
