Strap for Chronomat 44 Stainless Steel / Antarctica White / Rubber

The lug width of the Breitling Chronomat B01 44 AB011012.A690.145S is 22mm. This measurement is taken internally between the two lugs at the spring bar attachment point. It is a standard dimension for sport chronographs in this size range and offers broad compatibility with leather, rubber, NATO, and steel straps.

The most suitable materials for the Chronomat B01 44 are alligator leather in a glossy finish for a sporty-elegant look, vegetable-tanned calfskin for those who appreciate natural patina development over time, and vulcanised rubber for a tool-watch profile consistent with the model's 200m water resistance. A steel deployant clasp is the most appropriate fastening to complement the watch's value.

The strap is removed using a spring bar tool inserted into the gap between the strap and the lug. The 22mm spring bars compress laterally and slide out. No specialist watchmaking skills are required, but it is advisable to work on a soft surface to avoid scratching the case. With pre-fitted spring bars on the new strap, the whole operation takes under a minute.

Yes. Any strap with a 22mm attachment and slightly curved ends is compatible with the Chronomat B01 44. Milano Straps offers handcrafted straps in 22mm, available both from catalogue and bespoke, with finishes and materials selected to complement the stainless steel case. The slight curve of the Chronomat lugs requires pre-formed strap ends or sufficiently flexible material.

Longevity depends on the leather type and frequency of use. A quality vegetable-tanned calfskin strap worn daily typically lasts 18 to 36 months before showing structural wear. Premium alligator, being denser and more resilient, can exceed 3 to 5 years with proper care — leather conditioner and thorough drying after moisture exposure. Milano Straps straps carry an 18-month warranty against manufacturing defects.
