Yes, any strap with a 20 mm lug width and a taper from 20 to 18 mm is compatible with the Breitling Premier A45340241B1X3. It is important to check the strap end profile: the slightly tapered lugs of this reference pair best with a straight or gently curved strap end.

The longevity of a leather strap depends on the quality of the tanning process, daily use habits and maintenance. A high-grade vegetable-tanned calf or alligator strap, rotated with at least one other strap and kept away from prolonged moisture exposure, will retain its aesthetic and structural integrity for 3–5 years. Shell cordovan, owing to its dense fibrous structure, can last considerably longer.
