Strap for Chronomat 44 Stainless Steel / Rose Gold / Onyx Black Roman / Rubber

The lug width of the Breitling Chronomat B01 44 CB011012/B957/131S is 22 mm. This measurement is standardised across the entire Chronomat family and should be taken between the inner walls of the lugs using a digital calliper, excluding the thickness of the lugs themselves.

For this two-tone steel and rose gold reference, an alligator strap in tobacco, cognac or dark chocolate tones is the most coherent choice: the grain of the leather complements the warmth of the rose gold whilst preserving the technical character of the Chronomat. Alternatively, a vegetable-tanned calf strap in navy blue or dark brown offers daily versatility and develops a pleasing patina over time.

The strap on the Breitling Chronomat B01 44 is secured by standard 22 mm spring bars. Using a fine-tipped spring bar tool, compress the bar on one side and slide the strap free from the lug. No specialist tools are required, though it is advisable to consult a watchmaker or strap specialist to avoid scratching the rose gold case.

Yes, the Breitling Chronomat B01 44 accepts any aftermarket strap with a 22 mm lug width and standard spring bars. Milano Straps offers a curated selection of handcrafted 22 mm straps compatible with this reference, available in alligator, Tuscan calf, NATO and rubber, with various buckle options including deployant clasps.

The lifespan of a leather strap depends on the quality of the hide and daily care. A quality vegetable-tanned calf strap typically lasts 18 to 36 months with daily wear; an alligator strap, owing to the density of exotic leather fibres, can exceed 3 to 5 years if kept away from prolonged moisture and perspiration. All Milano Straps straps carry an 18-month warranty against manufacturing defects.
