Breitling Chronomat Automatic GMT 40 ref A32398101M1A1 (2022) is relatively new to the brand’s catalog coming to market in 2022 just a few years after the Chronomat collection was relaunched in 2020. While the series included a nice selection of design set options the case sizes were lacking that is until ref. A32398101M1A1 and its other variations came to market measuring 40mm. Now collectors can choose either 36mm 40mm or 42mm. This model also brings with it a new GMT function via the Breitling caliber 32 self-winding mechanical movement. Aside from these exciting upgrades ref. A32398101M1A1 is every bit the traditional Chronomat sans chronograph movement. It sports the iconic onion-shaped crown rouleaux-style bracelet and rider tab bezel.
