Strap for Chronomat 44 Stainless Steel / Mirage Red / Rubber

The lug width of the Breitling Chronomat B01 44 AB011012.K522.131S is 22 mm. To verify this on your own piece, measure the internal distance between the two lugs using a calliper: the correct value is exactly 22 mm.

For the Chronomat B01 44 with a 22 mm lug width, the most suitable materials are: polished alligator for formal occasions, vegetable-tanned calf leather for everyday wear with a natural patina, vulcanised rubber for sporting use, and ballistic nylon NATO for those who prefer the model's military heritage.

The strap is removed using a thin-tipped spring bar tool or a fork-style tool. Insert the tool into the lug notch, compress the spring bar and slide the strap free. This is a reversible operation requiring no specialist tools, though care should be taken to avoid scratching the case.

Yes. Any strap with a 22 mm attachment and standard spring bars is compatible with the Chronomat B01 44 AB011012.K522.131S. milanostraps.it offers a curated selection of handcrafted 22 mm straps in leather, NATO and rubber, designed specifically for this case size.

Strap longevity depends on the material and level of care. A quality vegetable-tanned calf strap typically lasts 2–3 years with daily wear; a well-maintained alligator strap can exceed 5 years. Avoiding prolonged exposure to water, perspiration and direct sunlight significantly extends the strap's service life.
