UMR Ruhla Combat Diver Watch KSU1302 Wristwatch Black • Limited Edition 001-499 • Original Caliber 13 Quartz Movement

The UMR Ruhla Combat Swimmer Watch 13-02 is a limited-edition reissue of the legendary diver's watch that was developed and produced in the 1980s by Uhrenwerke Ruhla (VEB) on behalf of the NVA for the combat swimmers and combat divers of the GDR armed forces. This replica is released in a strictly limited edition with serial numbers from 001 to 499 and features the original Caliber 13 movement, quartz-controlled and as authentic as the historical model.

The stainless steel case with a matte rotating bezel, screw-down case back, and screw-down crown ensures maximum durability and water resistance of up to 20 ATM. The green luminous dial with black numerals and a 2 mm thick mineral crystal give the watch its unmistakable diver style. The screwed-on rubber strap with a screwed-on steel buckle completes the professional look. Each watch comes with a faux leather box, a blue textile pull-through strap, a screwdriver, and a certificate of authenticity.
