Empire style year duration regulator by Jacob.

Ref: 1046


Empire style longcase regulator of the finest mahogany with a trunk door inset with a mercury barometer and a pair of thermometers.

Extremely fine and delicate 6 wheel train, weight driven movement with external escape wheel with dead beat escapement numbered 37.

Like Breguet Jacob supplied his regulators “en souscription” (by order) and supplied approximately 50 in his lifetime.

They came in a variety of case styles from quite plain and severe to this style which were his best.

The ormolu mounts are of the finest quality and the heavy silvered dial is extremely legible with conventional hours and minutes with central sweep seconds.
