ENDEAVOUR PERPETUAL CALENDAR

Our perpetual calendar is the ultimate in terms of simplicity and ingenuity.
A short arrow-shaped hand uses the hour indices to indicate the month. Thanks to the Flash Calendar system, the date change happens instantaneously at midnight. The time can be adjusted forwards or backwards at any moment without any risk to the movement.
This combination of exceptional solutions led the Endeavour Perpetual Calendar to be recognised at the Geneva Watchmaking Grand Prix in 2006, in the complicated watches category.

PERPETUAL FLASH CALENDAR

Our Endeavour 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 Endeavour Perpetual Calendar to be recognised at the Geneva Watchmaking Grand Prix in 2006.
