Notes

Like many of Breguet's watches from this period, the calibre of the movement is of an altogether special design. The addition of the thermometer is rare, and a small lever is provided in the edge of the dial, to stop the entire watch by locking the balance. The chronograph sequence is as follow with both hands running: Stop split hand/start chronograph hand with instantaneous re-unite. The flying 1/5th second's hand is driven from the going train.The bimetallic strip operates the thermometer through a lever with rack-andpinion.
