Strap for Chronomat B01 42 Stainless Steel / Platinum / Ice Blue

The lug width of the Breitling Chronomat B01 42 PB0134101C1S2 is 22mm. This measurement is taken between the inner walls of the case lugs and is the key parameter for selecting a compatible strap. Any strap with a 22mm attachment width will fit this reference correctly.

For the Chronomat B01 42 featuring platinum elements, the most suitable straps are smooth alligator in black or anthracite for formal occasions, or military-grain calf leather in dark brown for an aesthetic consistent with the model's aviation heritage. A brushed steel deployant clasp is the most appropriate fastening, providing visual symmetry with the case.

To replace the strap on the Chronomat B01 42, a flat-tipped spring bar tool is required to remove the spring bars from the 22mm lugs. The lugs on this model are straight, which makes the operation straightforward. It is advisable to work on a soft surface to protect the case, and if in doubt, to consult a watchmaker or visit the Casati Milano atelier.

Yes. Any 22mm strap with a straight end profile is compatible with the Chronomat B01 42. Milano Straps offers handcrafted straps in calf leather, alligator, shell cordovan and rubber, as well as technical nylon NATO straps, all produced specifically for the 22mm lug width and tested for geometric compatibility with Breitling lugs.

The lifespan of a leather strap depends on material quality, daily use and maintenance. A high-quality vegetable-tanned strap, kept away from water and excessive perspiration and regularly treated with leather conditioner, can last between three and five years while retaining a dignified patina. Milano Straps straps carry an 18-month warranty against manufacturing defects.
