Strap for Chronomat 44 Stainless Steel / Black - Roman / Calf

The lug width of the Breitling Chronomat B01 44, reference AB011011/B956/433X, is 22 mm. This measurement should be taken internally between the two lugs using a millimetre calliper, with the case resting flat on a surface. All 22 mm straps available on milanostraps.it are compatible with this reference.

For the Chronomat B01 44, a square-scale Louisiana alligator strap or a Tuscan vegetable-tanned calf leather strap offer the most balanced combination of aesthetics and durability. For sport or humid environments, a rubber or NATO strap is preferable. A deployant clasp is recommended to distribute the weight of the 44 mm case evenly across the wrist.

To replace the strap on the Chronomat B01 44, a spring bar tool is required. The 22 mm spring bars must be engaged in the lug slots on both sides of the case. It is advisable to rest the case on a soft cloth to avoid scratching the polished surfaces. The procedure takes only a few minutes and does not require specialist technical assistance.

Yes. Any strap with a 22 mm lug width is compatible with the Chronomat B01 44. milanostraps.it offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan, NATO and rubber, with customisable stitching and finishes. All straps are made in Italy using selected materials and come with an 18-month warranty against manufacturing defects.

The lifespan of a leather strap depends on the type of hide, frequency of use, and exposure to perspiration and water. A quality vegetable-tanned calf strap, with regular use and basic care, typically lasts 2 to 4 years. Shell cordovan, owing to its dense fibre structure, can exceed 5 years while retaining its shape and appearance. Alligator offers an intermediate lifespan but develops a highly desirable patina over time. Avoiding prolonged contact with water and sweat significantly extends the life of any leather strap.
