The model 6068 NK symbolises the special relationship that exists between our company and the town Nenkirchen in Saar, the birthplace of engineer Lothar Schmidt, owner of Sinn Spezialuhren. This watch expresses Lothar Schmidt’s affinity to his home town. To emphasise this, the watch, which is limited to 200 units, has a number of special features. The Neunkirchen coat of arms is imprinted on the transparent back, which is made of anti-reflective sapphire crystal glass. The transparent back beautifully shows off the exquisitely finished movement, which has engravings of the limited edition number and the Sinn logo on the rotor. The watch itself has a diameter of 38.5 mm and can display two time zones on a 12-hour basis. The case is made of polished stainless steel. The 6068 NK is waterproof up to 100 m (=10 bar) and resistant to low pressure.
