Notes

Self winding watches from this period, constr ucted with a bar caliber movement are extremely rare. This example is particularly interesting by virtue of the original layout of the bridges, allowing the platinum weight to oscillate on the side of the movement between two steel banking springs, an idea to reduce the thickness of the watch. The arm of the weight has a semicircular kink to act as a shock absorber. A similar arrangement was adopted by Breguet for the small series of self winding pocket watches, sold as a set with a minute repeating astronomical wristwatch in 1991.
