BREAKTHROUGH: 1815 RATTRAPANTE PERPETUAL CALENDAR
A. Lange & Sohne has transcended watchmaking with the 1815 Rattrapante Perpetual Calendar. It features the technical rattrapante or split-second chronograph function that measures lap times, a perpetual calendar designed to remain correct till the year 2100, and a lunar display that only needs correcting every 122 years. Time almost never stops with this watch.
The visually stunning timepiece has an amazing new movement made up of 636 parts. The split-second mechanism has two individual column wheels (ensuring precision and accuracy) – one for the chronograph and one for the rattrapante, which is activated by the button at 10 o’clock. All this magnificence is visible through the sapphire-crystal caseback and ranks among the most fascinating of watch movements.
On the elegant dial are Arabic numerals, a railway-track minute scale, gold and blue hands as well as four round subsidiary dials in a clover-leaf configuration.
Despite its complex mechanism, the 1815 Rattrapante Perpetual Calendar boasts a relatively petite, classic design – a signature of the 1815 watch family that has its roots in the brand’s grand pocket-watch tradition. Available in a platinum or rose gold case, this timepiece is a definite musthave for collectors who value both form and function.
