This is a very rare Aquastar Regate timer from the early 1970s. The monopusher chronograph is powered by the Aquastar refined Lemania 1345 automatic movement. you will be able to reset and start the 2 x 5 minute dot counter and the orange second hand over the one single pusher. if you don´t use the chrono function, the sweeping second hand just acts as the standart circulating second hand and the dot counters will stay black. the 38mm steelcase has never been polished and is in very nice condition. the rare black dial, as well as the handset are still carrying original tritium lume. superdomed plexi, pusher and starsigned crown are all the original ones. The watch comes on a new black leatherband with steel buckle. This beautiful toolwatch of the historical important diverwatch brand Aquastar has a stunning appearance on the wrist.
