Universal Genève was the most famous for producing these complicated chronograph-style of watches in the early part of the 20th century and it is not widely known that Breitling had its own version in the form of the Ref. 799. When it was released in the 40s, it was one of the most complicated watches on the market, featuring a moonphase, date and chronograph functions. Not many of these watches were produced, and many have been badly restored, making this unrestored example very rare and collectible.

Powered by a Venus Cal. 187, it is a manual-winding column wheel chronograph movement with a date and moon-phase module. Being known as a reliable calibre, it features a Glucydur balance wheel and a Breguet spiral mainspring, adding to its overall quality. The movement features an unmarked bridge, which is correct for the Ref. 799. The watch originally had a power reserve of approximately 44 hours.

This rare piece dates to around 1940 and was launched by Willy Breitling the son of Gaston Breitling. At the time, it was a very popular and sought after timepiece. Despite its commercial success, there were never many produced, largely due to the complication of the movement.
