Strap for Breitling for Bentley GMT Black

The lug width of the Breitling for Bentley A4736212.B919 is 20mm. To confirm this measurement before purchasing an aftermarket strap, it is advisable to measure the internal distance between the two lugs using a calliper, rather than relying on the overall case diameter which, at 49mm, can be misleading.

Given the strong visual identity of this chronograph, vegetable-tanned alligator leather is the most coherent choice: the three-dimensional grain complements the textured bezel and chronograph pushers. Alternatively, shell cordovan develops a distinctive patina over time, while box-calf leather in cognac or tobacco offers maximum versatility. For sportier contexts, vulcanised rubber maintains the instrument-oriented character of the piece.

The strap is removed using a flat or forked spring bar tool, applying gentle leverage to the spring bars housed within the lugs. On large-cased watches such as this Bentley, it is advisable to work on a soft surface and use a spring bar tool with a plastic tip to avoid scratching the polished lug ends. The operation requires no specialist equipment, though some familiarity with the process — or the assistance of a watchmaker — is recommended.

Longevity depends on the material and care routine. A quality alligator strap, conditioned periodically and kept away from prolonged exposure to perspiration and water, can last between three and five years whilst retaining its structural integrity. Shell cordovan is even more durable due to its dense fibrous structure. Box-calf leather typically lasts two to three years with daily wear. High-quality rubber straps are unaffected by moisture and can exceed five years of use.
