Why complicate matter?

31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31: the annual sequence of months is more complicated than it appears. In horological terms, its inconsistency must be addressed when designing an annual calendar such as our Saros, first introduced in 2012 with the Sky-Dweller.

Like all annual calendars, it autonomously differentiates months with 30 and 31 days and only requires to be set once every year, when February turns to March. Developing such a complication usually requires beautifully intricate mechanisms, with countless levers, cams and springs. But it is a different type of beauty that has always held our favour: that of simplicity. No matter how difficult it may be to reach. Here, it took us many years of development to finally make our annual calendar, using only four gear wheels and two gear ratios. Nothing more. Its conception is so efficient, the movement’s performance and durability are in no way affected. To the contrary, it allows for the energy dispensed by the feature to be perfectly managed. Perhaps that is why it is considered a horological prowess. The Saros is a most ingenious watchmaking complication.
