MANUFACTURE CALIBER OF THE EXTRA CLASS
Hanhart's own manufacture caliber 122 is used in the addition stopper. The wrist chronograph features the first-class AMT5100 M caliber from Sellita's ``Manufacture AMT`` department. The watch controls the chronograph via a control wheel. When fully wound, the stopwatch has a power reserve of at least 10 hours and the wristwatch has a power reserve of at least 58 hours. Both calibers are traditionally wound by hand. They are robust, reliable and a joy for every chronograph fan.
