In 2020, Breitling launched the revamped Chronomat B01 42. It's a fresh take on their classic model with a sharper case, redesigned bezel, and the choice of a stylish 'Rouleaux' bracelet. The watch houses Breitling's own B01 movement. Four years later, the AB0134721G1S2 joined the lineup. This particular Chronomat features a stainless steel case adorned with diamonds and a sleek black dial.
