Executed to perfection, the 1815 flyback chronograph is a statement to the industry of the level of precision and micro engineering that A. Lange & Söhne is capable of taking inspiration from the brand’s historic pocket chronographs, the 1815 chronograph debuted in 2004 and was available in an attractive combination of a white gold case paired with argenté dial and blued steel hands with the ref 401.026, as well as a pink gold version with matching pink gold hands on black dial with ref, 401.031. On the movement side, a horological metropolis from the L.951.0 can be witnessed composed of the firm’s signature German silver with a hand-engraved balance cock. Practically the same calibre as the Datograph with the absence of the big date mechanism, the movement and its architecture is perhaps where most would surrender to.

The collection had an evolution of a total of three generation with design nuances that sets them apart. Introduced with the ref. 401.026 measuring at 39.5mm, the design is kept rather simple and elegant featuring an attractive sloped outer ring that carries the pulsometer scale, logo and two recessed registers sitting slightly below the crown. Passing the baton with the discontinuation of the first generation, in 2010 A. Lange & Söhne took on a new minimalistic approach with the second generation ref. 402.026. Arguably being one of the purest execution amongst the three generations, the first and foremost obvious distinction from its siblings is the absence of the pulsometer scale. The present is part of the last generation released in 2017, reminiscent of the very first design, A. Lange & Söhne brought back the signature pulsometer scale, this time with larger register and bolder typography. Powered by the upgraded calibre L951.5, that power reserve is enhanced up to 60 hours of activities from a full wound.

The present example offered by the original owner is cased in 18K white gold fitted with a masculine all black dial is simply handsome. Perfection with a personality and incredible charisma, the present timepiece is offered with the full set of accessories, and preserved in excellent overall condition. A perfect additional for a purist collection, this monochromatic chronograph is a must have especially from the rising demand on A. Lange & Söhne timepieces.
