Breitling B01 Family Overview

Starting in 2017, Breitling began supplying a version of Cal. B01 to Tudor. The resulting movement, Cal. MT5813, has a free sprung balance with a silicon hairspring, as is common in modern Rolex and Tudor movements. It is also decorated differently. Strangely, it is often quoted as having different dimensions: 30.40 mm diameter and 7.23 mm thickness.
