A.Lange & Söhne is enriching its 1815 model family with a timepiece featuring one of the most sophisticated horological complications: The chronograph rattrapante.


This new model is fully focused on this complex complication and features a custom-developed movement.

Featuring a totally unique dial design and the finest in savoir-faire and manufactory the limited edition 1815 RATTRAPANTE has a platinum case and is available in just 200 pieces.


The complex mechanism of this watch expands the functionality of a classic chronograph by allowing the measurement of a random number of lap times within a minute. For this purpose, the watch has two superposed chronograph hands, the centre chronograph hand and the centre rattrapante hand. Both hands start together when the pusher at 2 o’clock is actuated. The centre rattrapante hand can now be stopped independently of the centre chronograph hand and then re-synchronised with it. This procedure, used for instance to measure lap times, can be repeated infinitely.

The design of this exquisite watch features a platinum case and bright argenté-coloured dial with contrasting dark blue hands. The traditional elements of the watch include the peripheral railway-track minute scale and prominent Arabic numerals.


By developing their own movement the watchmakers were able to have more freedom with the design elements of the watch, including choosing the positioning of the subsidiary dials which are placed at 12 and 6 o’clock, respectively, on the vertical centre axis. This symmetric arrangement gives the timepiece a balanced and expressive personality.

The watch is powered by the manufacture movement L101.2 which is entirely visible through the sapphire-crystal caseback.

Available in a limited edition of 200 pieces.
