Kriegsmarine ship´s clock by Kieninger & Obergfell from 2nd World war in very good condition

Very nice Militaria collector's item of the Kriegsmarine ww2

A piece of German history rarely found in this condition. Ship clock from Kieninger & Obergfell as they were found on all ships, including U-Boats. Up to six of these watches were used on submarines. On battleships up to 64. Very nice early piece with the number 340, naval acceptance and the assignment N / G (North Sea group). Later copies only with N and later in the war without. Center seconds. The 8-day movement works perfectly. Very nice patina of the brass case. No damages.

Upper diameter: 17 cm

Lower diameter: 20 cm
