Strap for Colt 36 Diamond / Pearl Diamond / Sahara

The lug width of the Breitling Colt A7438953.A771.214X is 18mm. This measurement refers to the internal distance between the lugs at the point where they meet the case, and is the critical parameter when selecting a compatible replacement strap. It is advisable to confirm this with a calliper on your own piece before ordering an aftermarket strap.

The ideal choice depends on the intended use. For sport or everyday wear, a vulcanised rubber or ballistic nylon NATO strap in 18mm offers durability and ease of maintenance. For formal occasions or to complement the quality of the case, a vegetable-tanned alligator strap with a brushed steel deployant clasp is the most refined option, fully consistent with the Colt's construction standards.

Strap removal requires a spring bar tool with a fine tip. Insert the tip into the gap between the lug and the strap end, compress the spring bar and slide the strap free. Care must be taken not to scratch the brushed surfaces of the case. If in doubt, it is advisable to entrust the operation to a qualified watchmaker or to the Casati Milano atelier during a fitting appointment.

Yes. Any strap with an 18mm attachment width and standard spring bars is technically compatible. Milano Straps offers a curated selection of handcrafted 18mm straps in various materials and finishes, manufactured to standards appropriate for high-end timepieces. It is also important to verify the strap length — short and long portions — according to your wrist circumference.

Longevity depends on the material and frequency of use. A mid-grade calfskin strap typically lasts 12 to 24 months with daily wear. An alligator strap with vegetable tanning or a shell cordovan strap, thanks to the density of their fibres, can last 3 to 5 years or more if rotated with other straps and kept away from prolonged exposure to perspiration and moisture. Milano Straps offers an 18-month guarantee against manufacturing defects.
