The reference # - B13050.1 - gives it away as a Chronomat, but Breitling doesn't make it easy by having multiple color variations and styles all share the same model number. They'll also keep the same model number over several years while introducing still more variations and even changing the details on the dial, etc. They do it across multiple lines.
A very nice watch! Chronomat Vitesse - ref B13050
