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

The Breitling Chronomat B01 44 CB0110AA.C790.375C features a native lug width of 22mm. This measurement is consistent between both lugs and should be verified with a calliper by measuring the internal distance at the case, to ensure accurate compatibility with any aftermarket strap.

For the rose gold and stainless steel two-tone variant, an alligator strap in vegetable-tanned leather in Havana Brown or Cognac tones is the most aesthetically coherent choice, complementing the warm rose gold components. Alternatively, a smooth calf leather strap in anthracite or midnight blue enhances the contrast with the steel. For sporting use, a rubber strap with lateral grip texture is the most functional option.

Strap replacement requires a fine-tipped springbar tool to remove the spring bars securing the strap to the lugs. It is advisable to work on a soft surface to protect the rose gold and steel case. Standard spring bars with a 1.8mm diameter are compatible with the lugs of the Chronomat B01 44.

Yes. Any aftermarket strap with a 22mm attachment is compatible with this reference. Milano Straps produces handcrafted straps in 22mm, available in alligator, calf leather, NATO nylon and rubber, with stitching and thickness calibrated to fit the lugs of the Chronomat B01 44 precisely.

The lifespan of a leather strap depends on the material, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned alligator strap, used with care and rotated regularly with other straps, can last between 3 and 5 years while maintaining structural integrity and developing a characteristic patina. Milano Straps straps are covered by an 18-month warranty against manufacturing defects.
