This model was introduced in 2018. The dial is crafted from solid silver. The hands are made of blued steel.

The 1815 CHRONOGRAPH unites traditional elements with latest-generation technology. The calibre L951.5 movement enhances the mechanism of the precisely jumping minute counter with a comfortable flyback function. This makes it possible to instantaneously reset the chronograph hands to zero during an ongoing measurement simply by actuating a button, and to immediately start a new measurement by releasing it.

The dial layout is well-organised and functional as in A. Lange & Söhne’s historic pocket chronographs. Slightly shifted below the horizontal centreline, the two subsidiary dials emphasise the classic origins of the watch, as does the characteristic railway-track minute scale. The additional graduation on the minute scale allows readings of stopped times to an accuracy of one-fifth of a second. Pulse rates can be determined with the pulsometer scale on the outer ring of the dial.
