Notes

Note: Like many of Breguet watches from this period, the caliber of the movement is of an altogether special design. The addition of a thermometer is rare, and a small lever is provided, in the edge of the dial, to stop the entire watch by arresting the balance. The chronograph sequence is as follows with both hands running: Stop split hand/stop chronograph hand/ start chronograph hand with instantaneous re-unite. The Flying 1 /5th seconds hand is driven from the going-train. A bimetallic strip operates the thermometer through a lever terminating with a rack-and-pinion.
