This is the third Lange wristwatch with a fusée-and-chain transmission and continues the tradition of watches that are fully focused on precise time measurement.
This horological rarity with its three-part enamel dial has famous historic forebears.
The pocket chronometer – the timepiece of the scientific elite – has always been a coveted rarity.
It dates back to around 1880 at A. Lange & Söhne, when Richard Lange, the company founder's oldest son and technical director of the family business, was already inspiring the craft of precision watchmaking.
Overall, only about 30 of these unusual timepieces were ever made. 
Now, the chronometer with a fusee and chain transmission is experiencing a renaissance, as an exclusive timekeeping instrument for the wrist dedicated to mechanical precision – its name: RICHARD LANGE Pour le Mérite.

This model in 18K Rose gold has a beautifully legible, radiant white enamel dial with blued steel hands which are in perfect contrast.
