Notes

Front cover with an engraved foliate monogram highlighted with red, blue and white enamel.

The present watch is of high quality and is particularly interesting because it exhibits a very rarely found and sophisticated horological feature. The perpetual calendar with retrograde date is extremely uncommon and was made by very few workshops, among them H. R. Ekegren, Breguet and Marius LeCoultre
