Oak cased month duration regulator by Strasser & Rohde

Ref: 1064


Extremely rare month duration regulator by Strasser & Rohde No.237 dating from 1900.

Early style oak case used by Strasser & Rohde on their exhibition stands at world trade fairs in the late 19C.

Strasser & Rohde regularly supplied unsigned regulators to independent clockmakers who would then sign it for themselves.

Superb quality movement with a 5 wheel train, jewelled dead beat escapement and Harrison’s maintaining power. The movement sits on a very heavy brass bracket that incorporates a separate pendulum support. The whole of the wheel train and Strasser’s signature canted crutch have a silver gilt frosted plating, a finish most often found on the best quality watch movements.

The pendulum is the early grid iron type by Grossman, superbly made, that has coarse adjustment via a pin in the central zinc rod or by a knurled rating nut. Fine adjustment is achieved by dropping or removing tiny ball bearings from a brass cone shaped container on the central bridge.

Both the heavy brass silvered dial and back plate of the movement are punch numbered 237 which equates to a date, according to the book on German precision clocks by Jurgen Ermurt, of 1900.
