Perpetual time: 4 modern watches with a perpetual calendar

In today's watch industry, a perpetual calendar displays the date and automatically adjusts to months of less than 31 days and leap years. Usually, perpetual calendars require manual adjustment only three times in 400 years (for example, in 2100, 2200, 2300, but not 2400), however, nothing is impossible for an engineering genius, which is why there are rare models with a truly perpetual calendar. Often times, the calendar is combined with other complications such as a moon phase indicator. So, we present to your attention four models of watches that are ready to work forever (or almost forever).

The list opens with a Patek Philippe Perpetual Calendar Ref. 5940. The stylish cushion-shaped case in rose gold hides the ultra-thin caliber 240 Q, equipped with a micro-rotor. The dimensions of the case are 37 x 44,6 mm.

The next model - Audemars Piguet Royal Oak Perpetual Calendar - was presented at SIHH 2017. The watch in a black ceramic case with the same bracelet is 41 mm in diameter and hides the self-winding caliber 5134.

The A. Lange & Söhne Tourbograph Perpetual “Pour le Mérite” has a much more decorated and rich dial than previous versions. The signature hand-wound caliber includes five major complications: a perpetual calendar, a chronograph, a rattrapant (split chronograph), a chain fuse and a tourbillon. The watch in a 43-mm platinum case is limited to 50 pieces.

And yet another representative of the “perpetual” watch - the Glashütte Original Senator Excellence Perpetual Calendar with the proprietary automatic caliber 36 - has come closer to eternal work, perhaps more than anyone else, because it provides a 100-hour power reserve. The model is presented in two versions of a 42-mm case: steel and rose gold.
