Strap for Colt Quartz Volcano Black / Rubber / Pin

The Breitling Colt A7438811/BD45/227S/A20S.1 has a lug width of 22mm. This measurement refers to the internal distance between the two lugs at the strap attachment point. It is the determining specification when selecting a compatible strap: any 22mm-wide strap will fit correctly.

For the Breitling Colt 44mm, the options most consistent with the watch's character are: a vegetable-tanned alligator strap with a matte finish for formal settings, box grain calf leather for everyday wear, a ballistic nylon NATO for its original operational vocation, and vulcanised rubber for sport or diving use. The correct width is always 22mm.

To replace the strap on the Breitling Colt A7438811/BD45/227S/A20S.1, you will need a forked or pointed spring bar tool, available at any watchmaker. Compress the spring bar between the lugs and slide the strap free. The operation takes under five minutes and poses no risk to the case if carried out with the correct tool. It is advisable to work on a soft surface to prevent scratching the lugs.

Yes, the aftermarket offers a wide selection of straps compatible with the Breitling Colt 44mm, provided they conform to the 22mm lug width specification. Milano Straps manufactures handcrafted leather, rubber, and nylon straps specifically sized for this reference, with finishes and materials chosen to complement the 44mm stainless steel case.

The lifespan of a leather strap depends on the material, usage, and care. A quality calf leather strap with reinforced stitching has an average life of 18 to 24 months with daily wear. Vegetable-tanned alligator, owing to its dense fibrous structure, tends to last over 36 months whilst developing a distinctive patina. It is recommended to avoid prolonged exposure to water and to treat the leather periodically with a neutral, silicone-free conditioner.
