Strap for Colt 36 Diamond / Pearl / Sahara

The lug width of the Breitling Colt A7438953.A772.239X is 18mm. This measurement determines the correct strap width at the point where it attaches to the case. It is recommended to verify this with a digital calliper before purchasing a replacement strap.

The lifespan of a leather strap depends on the material, maintenance and frequency of use. A vegetable-tanned calf strap with regular care lasts between 2 and 4 years. Shell cordovan often exceeds 5 years owing to its dense fibre structure. Alligator, when treated with neutral conditioners and kept away from prolonged moisture, maintains structural and aesthetic integrity for 3 to 6 years. Casati Milano straps carry an 18-month manufacturing defect guarantee.
