Strap for Premier B01 Chronograph 42 Stainless Steel / Black / Bracelet

The lug width of the Breitling Premier AB0118371B1A1 is 22 mm. This measurement is taken internally between the two case lugs using a digital calliper placed against the spring bar. It is advisable to verify the actual measurement before ordering an aftermarket strap, as manufacturing tolerances may vary by ±0.1–0.2 mm.

For the Premier AB0118371B1A1, given its dressy-sport aesthetic, the most appropriate strap is a 22 mm belly-cut alligator with a polished or semi-polished finish, paired with a deployant clasp. Alternatively, a vegetable-tanned calfskin strap represents a more everyday option that develops a distinctive patina over time, entirely consistent with the vintage-contemporary spirit of the model.

The strap on the Breitling Premier AB0118371B1A1 is secured by standard 22 mm spring bars. Replacement requires a spring bar tool or a fine-tipped fork tool: compress the spring bar inside the lug, remove the strap, and insert the new one using the same procedure. The operation does not require opening the case or advanced watchmaking skills.

Yes. Any strap with a 22 mm attachment and standard spring bars is compatible with the Breitling Premier AB0118371B1A1.

The lifespan of a leather strap depends on the type of leather, daily use, and care. A quality vegetable-tanned calfskin strap, worn regularly, typically lasts 2–4 years before requiring replacement. High-grade alligator or shell cordovan straps can exceed 5 years with proper maintenance — periodic application of leather conditioner and rotation with other straps. Prolonged exposure to perspiration and water is the primary factor of deterioration.
