Strap for Colt Quartz Mariner Blue / Rubber / Pin

The lug width of the Breitling Colt A7438811/C907/228S/A20S.1 is 22mm. This measurement is taken internally between the two lugs at the point where the case meets the bracelet, and should be verified using a millimetre calliper for accuracy.

For the Breitling Colt A7438811/C907/228S/A20S.1, the most suitable options are a nylon NATO strap for operational use, vegetable-tanned calf leather for everyday formal wear, matte alligator for semi-formal settings, and vulcanised rubber for sports or aquatic activities. A stainless steel deployant clasp is recommended for those seeking maximum security.

To replace the strap, you need to remove the spring bars securing the bracelet to the case lugs. Use a dedicated spring bar tool or a fork-tip screwdriver: compress the spring bar, release one end from the lug and slide the strap free. Take care not to scratch the stainless steel case; if unfamiliar with the process, it is advisable to consult a watchmaker.

Yes, any strap with a 22mm lug width is compatible with the Breitling Colt A7438811/C907/228S/A20S.1. Milano Straps offers a range of handcrafted 22mm straps in various materials, including calf leather, alligator, NATO and rubber, all hand-finished with customisable options.

The lifespan of a leather strap depends on the material, frequency of use and maintenance. A quality vegetable-tanned calf strap used daily and kept away from excessive perspiration and water can last between 2 and 4 years. Alligator, owing to the greater resilience of exotic leather, can exceed 5 years with proper care. Milano Straps provides an 18-month guarantee against manufacturing defects.
