A. LANGE & SÖHNE: A Legacy of Excellence
A. LANGE & SÖHNE has established itself in the luxury watch industry through the combination of innovative mechanisms with timeless design. The 1815 RATTRAPANTE PERPETUAL CALENDAR in white gold demonstrates this approach: a manually wound watch with a rattrapante chronograph function and perpetual calendar display, powered by the L101.1 caliber.
Unveiling the 1815 RATTRAPANTE PERPETUAL CALENDAR
Design and Aesthetics
The 1815 RATTRAPANTE PERPETUAL CALENDAR in white gold presents a refined aesthetic. The white gold case maintains classical proportions while the dial organizes multiple sub-dials for the calendar mechanism, chronograph functions, and subsidiary displays. The layout reflects the traditional Lange approach to dial architecture, with clear separation of complications across the face.
Movement: The Heart of the Timepiece
The L101.1 movement powers this watch. This manually wound caliber contains the perpetual calendar and rattrapante mechanisms, assembled in-house at the Glashütte manufacture. The movement achieves high accuracy through conventional escapement design and traditional hand-finishing techniques applied to the bridges and balance cock.
Complications That Impress
The rattrapante function operates as a split-seconds chronograph, allowing the wearer to time two simultaneous events by triggering the first hand, then pressing the rattrapante button to start a secondary hand that catches up and can be stopped independently. The perpetual calendar automatically accounts for leap years and variable month lengths, requiring no correction until the year 2100.
Why Choose the 1815 RATTRAPANTE?
This watch addresses collectors interested in calendar complications and chronographic functionality combined in a single reference. The perpetual calendar mechanism and rattrapante chronograph represent core Lange technical focuses, and the white gold case positions the watch within the manufacture’s formal collection tier.
