Strap for Chronomat B01 42 Red Gold / Green / Rubber

The lug width of the Breitling Chronomat B01 42 RB0134101L1S1 is 22mm. This measurement refers to the distance between the two lower lugs of the case, where the strap is fitted. It is advisable to verify this with a digital calliper before purchasing an aftermarket strap, as even minor discrepancies can affect the fit.

For the Chronomat B01 42 in red gold, the most suitable materials are Mississippiensis alligator in cognac or havana, shell cordovan which develops a warm patina over time, and Tuscan vegetable-tanned calf leather for everyday use. A deployant clasp in red gold or gold-tone PVD completes the pairing in a manner consistent with the precious case.

The strap on the Breitling Chronomat B01 42 is replaced using a flat or forked spring bar tool. The 22mm spring bars are released by pressing the tips inward towards the inside of the lug. As the case is in 18-carat red gold, it is essential to protect the surfaces during the operation by using a tool with a coated tip or placing a soft cloth between the tool and the case.

Yes, the aftermarket offers a wide selection of straps compatible with the 22mm lug width of the Chronomat B01 42. Milano Straps crafts handmade straps in leather, alligator and shell cordovan specifically dimensioned for this model, with curved ends to suit the profile of the lugs. It is important to ensure that the chosen strap has the correct taper and 22mm spring bars.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear and the care it receives. A quality vegetable-tanned calf strap will typically last between 2 and 4 years with regular use. Alligator, thanks to the compact structure of its scales, can exceed 4 to 5 years. To prolong its life, avoid prolonged contact with water, periodically apply a neutral conditioner, and rotate between multiple straps over time.
