Top Time B31- Green Leather/Green Dial

Newly launched in 2025, the Top Time B31 marks the debut of the Manufacture B31 movement at Breitling. A 38mm case, true to Top Time DNA, for an impeccable style that will fit every wrist. The Top Time B31 blends retro aesthetics with a modern edge. Its dial design takes inspiration from classic-car dashboard clocks, while its 38 mm case strikes a balance between vintage proportions and contemporary design, perfect for any wrist thanks to its universal size. Three colorways—green, blue, or a two-tone combination of white and sky-blue—pair with either a three-row stainless-steel bracelet or a perforated calfskin strap that gives a nod to racing gloves. Whether cruising the open road or simply embracing the everyday, this watch is a celebration of individuality and adventure.
