1940s Breitling Venus-175 Clamshell 36mm Chronograph Rare Black Gloss Snail Dial

This is a rare black snailed dial Breitling Clamshell Chronograph with the famous Venus 175 manufactured in the early 1940s. The case is a 4-bismuth early type waterproof case called clamshell, which was used by many brands, and the black gilt dial with a dense and complicated design that includes a telemeter and snailed tachymeter by grounding, which is different from Breitling's standard models such as the Chronomat and Navitimer. It is a precious gem with a different taste from Breitling's classic models such as the Chronomat and Navitimer. It is equipped with Venus's famous Cal. 175, which was also used in the Chronomat of the same era.
