Frequently asked questions

What is the lug width of the Breitling Colt A1338811/G804/157S/A20D.2?

The lug width of the Breitling Colt A1338811/G804/157S/A20D.2 is 22mm. This measurement corresponds to the internal distance between the two lugs of the case and determines compatibility with any aftermarket strap. It is advisable to verify this with a calliper before purchasing a replacement strap.

What is the best strap for the Breitling Colt A1338811/G804/157S/A20D.2?

For the Breitling Colt A1338811/G804/157S/A20D.2, the ideal choice depends on the context of use. A vegetable-tanned calf leather strap with a matte finish is the most versatile option for daily wear. For more formal occasions, a matte hornback alligator strap complements the brushed case beautifully. For sport or humid environments, a vulcanised rubber strap offers the best functionality. A NATO nylon strap remains true to the model's original military identity.

How do you change the strap on the Breitling Colt A1338811/G804/157S/A20D.2?

To change the strap on the Breitling Colt A1338811/G804/157S/A20D.2, the spring bars must be removed from the lugs using a fine-tipped spring bar tool. It is recommended to work on a soft surface to protect the case from scratches. Standard 22mm spring bars are inserted into the new strap's keepers and then secured under spring tension into the lug holes. The procedure takes approximately two minutes and requires no specialist watchmaking assistance.

Are there aftermarket straps compatible with the Breitling Colt A1338811/G804/157S/A20D.2?

Yes, any strap with a lug width of 22mm is compatible with the Breitling Colt A1338811/G804/157S/A20D.2, provided it is fitted with standard spring bars. Milanostraps.it offers a curated selection of handcrafted straps in various leathers and materials, all produced to the 22mm specification, ensuring a precise fit without any modification.

How long does a leather strap last on the Breitling Colt A1338811/G804/157S/A20D.2?

The lifespan of a leather strap depends on the quality of the material and the care taken in maintenance. A quality vegetable-tanned calf leather strap, kept dry and conditioned periodically with appropriate leather creams, can last between three and five years with daily use. A high-grade alligator strap, owing to the natural structure of its scales, tends to be more resistant to wear and develops a patina over time that enriches its appearance. Casati Milano straps are covered by an 18-month guarantee against manufacturing defects.
