Strap for Chronomat 44 Stainless Steel / Frecce Tricolori / Rubber

The lug width of the Breitling Chronomat B01 44 AB01104D.BC62.153S is 22mm. This is the standard measurement used by Breitling across the entire Chronomat 44 family, and can be verified with a digital calliper measuring the internal distance between the two lugs closest to the case.

For the Chronomat B01 44 AB01104D.BC62.153S, a perforated rally calf leather strap or a glossy alligator strap in black offers the most coherent pairing with the technical aesthetic and 44mm stainless steel case. For sporting use or humid environments, vulcanised rubber or a nylon NATO strap are functionally sound alternatives.

The strap on the Chronomat B01 44 is removed using a spring bar tool — either a fork-tip or pointed-tip model — to release the spring bars from the lug slots. It is advisable to work on a soft surface to protect the case finish. The operation requires no specialist tools and can be completed independently in a matter of minutes.

Yes. Any strap with a 22mm lug width and standard spring bars is compatible with the Chronomat B01 44 AB01104D.BC62.153S. Milano Straps offers handcrafted straps in various leathers and finishes, with the option of a pin buckle or deployant clasp, retaining or replacing the original Breitling hardware.

The lifespan of a leather strap depends on the type of hide, frequency of wear, and level of care. A quality vegetable-tanned calf strap worn daily typically lasts 12 to 24 months. Alligator leather, being denser and more resistant to flexion, can last 2 to 4 years. Avoiding prolonged exposure to water and perspiration significantly extends the strap's service life.
