German-based watchmaker A. Lange & Söhne makes very expensive, quality watches. Some of their watches sell for millions. In spite of the prices, they have amassed quite a cult following of fans. Their line of 1815 Chronographs was added to the lineup in 2004 and are some of the most sought after timepieces in the world. They quickly attract high-end buyers.
Now, there is a new and surprising addition to the 1815 line—an 1815 Chronograph with a black and a solid silver dial and a 39.5mm white gold case. This is the first time that A. Lange & Söhne has made a black pulsation dial in a white metal case. The result is fantastic though.
The watch features an L951.5 movement, which was last updated in 2010. It features a 60-hour battery power reserve and a balance spring. With a beat frequency of 18,000 semi-oscillations per hour, this watch measures time to within an accuracy of one-fifth of a second. A pulse rate scale is located on the dial. It is graduated for from 40 to 200 beats. When 30 beats are measured, the scale conveniently and accurately indicates the heart rate per minute.
This watch features the same Chronograph spectacular calibre as the Datograph but lacks a date function. Because it lacks the large Datograph, the newest addition to the 1815 family is relatively slim at just 11mm high.
Characterised by contrasts of black and white, this watch features a solid white gold Lange buckle and a black leather alligator strap.
