Strap for Breitling for Bentley GT Navy

The Breitling for Bentley A1336313.C649 has a lug width of 22 mm. This measurement should be taken internally between the lugs using a digital calliper positioned at the point of contact with the strap. It is a common width in Breitling's upper range, but we always recommend verifying before purchasing a replacement strap.

For this 44.8 mm sport-luxury chronograph, a Hornback alligator strap with vegetable tanning is the most coherent choice: the natural grain complements the complexity of the dial. Alternatively, Tuscan box-calf develops an authentic patina over time. For sporting use, vulcanised rubber with a grained texture offers excellent durability and comfort. A brushed steel deployant clasp is recommended to reduce wear on leather straps.

Strap replacement requires a fine-tipped spring bar tool (preferably with a forked tip) to release the spring bars from the lugs. The Breitling for Bentley lugs are deep and robust: it is advisable to work on a watchmaker's cushion to protect the case finishing. If you are not confident performing this operation, a watchmaker or the Casati Milano atelier service can carry it out safely.

Yes. Any strap with a 22 mm attachment width and standard spring bars (1.5 mm diameter) is technically compatible. Milano Straps offers handcrafted 22 mm straps made to measure with selected leathers, suitable both aesthetically and dimensionally for this model. It is also worth verifying the spring bar length (typically 20 mm for this case) to ensure a proper fit.

Longevity depends on the leather type and conditions of use. A vegetable-tanned calf strap, kept away from water, excessive perspiration and direct UV exposure, typically lasts 2–4 years while retaining structural and aesthetic integrity. Alligator, owing to its natural density, can exceed 5 years with proper care (nourishing cream every 3–4 months). Vulcanised rubber straps are unaffected by moisture and last considerably longer in sporting contexts.
