Strap for Chronomat 44 Stainless Steel / Rose Gold / Diamond / Metallica Blue / Croco

The lug width of the Breitling Chronomat B01 44 reference CB011053.C790.731P is 22 mm. This measurement is taken between the case lugs at the point of strap insertion and is consistent across all compatible straps and bracelets for this reference.

For the steel and rose gold variant, a grain carré alligator strap in cognac or tobacco tones complements the warm hue of the metal. Alternatively, a Tuscan calf leather strap with racing perforation or a two-tone technical NATO highlight the Chronomat B01 44's sporting identity without compromising its aeronautical character.

The strap on the Chronomat B01 44 is removed using a spring bar tool — either a flat-head screwdriver or a dedicated fork tool — to compress the spring bars housed between the case lugs. The operation requires no specialist watchmaking skills but should be carried out on a soft surface to avoid scratching the case. Standard 22 mm spring bars are widely available.

Yes. Any strap with a 22 mm attachment width is technically compatible with the Chronomat B01 44. Milano Straps offers a curated selection of handcrafted straps in various materials — alligator, calf leather, shell cordovan, rubber, NATO — made to order or available from stock, all supplied with spring bars and certified for this lug width.

The lifespan of a leather strap depends on the quality of the tanning process, frequency of use, and exposure to perspiration and moisture. A high-quality vegetable-tanned strap, worn daily on rotation, typically lasts 2–4 years. Regular conditioning with appropriate leather care products and alternating between straps can significantly extend this estimate. Milano Straps provides an 18-month warranty against manufacturing defects on all its straps.
