The Breitling Chronomat Colt 44 was introduced in 2018. While the case appears largely unchanged compared to the previous generation, the dial is substantially cleaner - not in small part caused by the simpler 'B' logo. It should be noted that this generation of the Colt is part of the Chronomat family, where it stood on its own before. Reference A1738810.CA06.173A has a blue dial. It is fitted with a stainless steel bracelet.
