Wempe Glashütte I/SA Zeitmeister Sport Diver’s Chronograph Bronze

The diver’s watches from Wempe’s Zeitmeister line are reminiscent of the military watches produced by Wempe in the 1960s. These diver’s watches are the first certified German chronometers for this underwater sport. This version of the Zeitmeister Sport Diver’s Chronograph is limited to 100 pieces. Its solid bronze case and bezel puts it firmly in the company’s nautical tradition and evokes ship’s propellers and the high-quality ship’s bells on the decks of historical oceangoing steamships.

The diver’s watches have the classic Zeitmeister shape, with long strap lugs that curve downward and side guards to protect the screw-in crown. They are water-resistant to 30 bar. This diver’s chronograph, with a robust diameter of 45 millimeters, has a stopwatch function for seconds that is located in the center of the dial. The stopwatch functions for minutes and for up to 12 hours are located on recessed auxiliary dials at the 12 and the 6. A permanent small seconds subdial at the 9 allows to check the watch’s function. The use of solid bronze for the case gives this timepiece a distinctly instrumental character.

Following on the special models with a Cermet bezel and a black DLC coating, this model varies not only the material but also the design of the watch. In previous models the numerals are smoothly set into the unidirectionally rotatable ceramic bezel, but in this model they boldly protrude. The Sport Diver’s Chronograph Bronze has a brown dial with gold-plated hour markers and hands, which emphasize the historical forerunners of the watch, as does the brown alligator-skin strap.

The screwed-in case back of the watch consists of titanium and bears a high-relief engraving of the Glashütte observatory, where every Zeitmeister diver’s chronograph has to pass the official chronometer test. To this end, the model is equipped with a balance cock specially designed by Wempe and a fine adjustment mechanism.
