Girard-Perregaux Constant Escapement L.M. 93500-52-731-BA6D

Girard-Perregaux built the Constant Escapement L.M. to solve a problem that has troubled watchmakers for centuries ? maintaining constant force as a mainspring unwinds ? and this 93500-52-731-BA6D reference houses that innovation inside a 48mm rose gold case with a white dial. Sapphire crystal and 100m water resistance sit alongside an automatic movement, and the watch closes on a leather strap suited to its haute horlogerie status.
