The name of Beaure appears to be unrecorded but he was evidently a maker who was active in either France or Switzerland and judging by the present watch, he was an extremely able maker. The influence of Breguet is quite evident in the functional layout, sturdy design and high finish of each mechanical part and in the use of the parachute shock absorber, temperature compensation curb and secret signature – all classic Breguet inventions. Continental watches using a combination of duplex escapement and fusee and chain are quite uncommon and this would suggest that Beaure had some knowledge of English watches also. The wheel train of this watch is made from a white metal alloy which is as yet unidentified.
