Strap for Chronomat 44 Stainless Steel / Pearl Roman / Rubber

The lug width of the Breitling Chronomat B01 44 AB011012.A691.131S is 22mm. This measurement is consistent across the entire Chronomat B01 44 family, ensuring full compatibility with any aftermarket 22mm strap, including those fitted with a deployant clasp.

Three strap types are particularly well-suited to the Chronomat B01 44: vegetable-tanned alligator leather for a refined, dressy register; perforated calf leather in a rally style, which echoes the model's racing heritage; or vulcanised rubber for aquatic and sporting use. The ideal choice depends on the intended context and the desired chromatic pairing with the black dial.

The Chronomat B01 44 uses standard 22mm spring bar lugs. Replacement requires a spring bar tool or a lug removal lever: compress the spring bar on one side of the lug, remove the existing strap, then fit the new one ensuring both spring bars click securely into place. No watchmaker's intervention is required.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear and exposure to perspiration and moisture. A quality handcrafted alligator or calf strap, with regular use and appropriate care, typically lasts between 18 and 36 months. MilanoStraps straps carry an 18-month guarantee against manufacturing defects.
