The Perpetual Calendar is an exceptional watch equipped with a number of ingenious features, such as an instantaneous date change – the Flash Calendar – which allows the watch to be adjusted forwards or backwards without risk of damaging the movement. Distinguished with the Geneva Watchmaking Grand Prix, this watch is truly extraordinary.
PERPETUAL FLASH CALENDAR
Our Perpetual Calendar is best known for its simple design. It shows only the time, date, month and power reserve. It compensates mechanically for the differing number of days in the months, hence the name perpetual. The sapphire crystal case-back reveals the H. Moser HMC 341 movement as well as the leap year cycle. The remarkable design of the Perpetual Calendar is possible in part due to the ingenious display for the month: this short central arrow hand uses the 12 hour indices to indicate the month. The H. Moser big date display is also very rare in that it is a flash calendar, generating the power to change the date in a fraction of a second. This combination of exceptional solutions led the Perpetual Calendar to be recognised at the Geneva Watchmaking Grand Prix in 2006.
