Strap for Chronomat 44 Stainless Steel / Rose Gold / Diamond / Metallica Brown / Calf

The lug width of the Breitling Chronomat B01 44 CB0110AA.Q576.433X is 22mm. This measurement is consistent across the entire Chronomat B01 44 family and allows the use of any aftermarket strap — leather, nylon or rubber — with a 22mm attachment.

For the two-tone steel and rose gold variant, the most suitable materials are belly alligator in bordeaux or midnight blue, and natural shell cordovan. Both complement the case without competing visually with the rose gold. A deployante clasp in brushed steel or rose gold PVD is preferable to a standard pin buckle to distribute the weight of the 44mm case evenly.

To replace the strap on the Chronomat B01 44, a fine-tipped spring bar tool is required. The lugs on this model have an angled geometry with sharp edges: care should be taken to avoid scratching the bezel. Alternatively, a watchmaker or the Casati Milano atelier can carry out the replacement during a scheduled appointment.

Yes. Any strap with a 22mm attachment and standard length (120/75mm or 130/80mm depending on wrist size) is compatible with the Chronomat B01 44. On milanostraps.it, handcrafted straps in alligator, calf leather, shell cordovan and nylon are available, specifically selected for 22mm lugs, with deployante or pin buckles in steel and rose gold.

The lifespan of a leather strap depends on the quality of the hide, care and daily use. A handcrafted alligator or shell cordovan strap, kept away from prolonged moisture and treated periodically with leather conditioner, can last between 3 and 5 years with regular wear. Milano Straps straps are covered by an 18-month warranty against manufacturing defects.
