Patek Philippe’s first chronograph wristwatch launched in 1923. Even back then it had a split-second mechanism. 17 years later, in 1940, the Geneva brand designed a chronograph with world time, pulse and respiration scales. A year later, the famous 1518 chronograph with perpetual calendar was launched. Adding complications to a chronograph is clearly one of the brand’s specialities so it’s no surprise that they’ve now added an annual calendar! This function was invented in the 1980s and only became popular in 1996 when Patek Philippe produced a simplified version of it. Halfway between the time-consuming simple calendar (which has to be reset five times a year) and the pricey perpetual calendar (which has to be reset in 2100), the annual calendar is among the brand’s bestsellers alongside the chronograph. The 42mm titanium timepiece is available with a navy or black dial. Price: 69’000 CHF
