Description of the clock:
Astronomical precision pendulum clock D353, nickel ray-pendulum with layering compensation No. 1737 - type Jsch (DRPNo 100870) from 1912 with Riefler spring force escapement (DRP No: 50739), airtight case with copper cylinder from Clemens Riefler.
Disassembling and cleaning of the movement, manufacturing the gold-contact spring for electrical minute winding mechanism, assembly, oiling and adjustment of the movement, adjustment of performance with a result of 0,029 s/d performance variation.
movement assembled on the copper cylinder, movement Riefler precision pendulum clock with spring force escapment and liftign and resting wheel
