Strap for Colt 36 Stratus Silver / Bracelet

The Breitling Colt A74389111G1A1 has a lug width of 18mm. This measurement refers to the internal distance between the case lugs and determines the exact strap width required. We recommend using a digital calliper to verify this before purchasing any aftermarket strap.

For the Breitling Colt A74389111G1A1, the most suitable materials are vegetable-tanned calf leather for everyday wear, matte alligator for more formal occasions, and technical nylon NATO or vulcanised rubber for sport or humid environments. The stainless steel case pairs naturally with satin or matte finishes.

The strap on the Breitling Colt A74389111G1A1 is secured with standard 18mm spring bars. A fine-tipped spring bar tool is sufficient to compress the spring bar ends and slide the strap free from the lugs. This can be done independently with care, or entrusted to a watchmaker or the Casati Milano atelier to avoid scratching the case.

Yes, the Breitling Colt A74389111G1A1 uses a standard 18mm lug attachment, compatible with a wide range of aftermarket straps. Milanostraps.it offers a curated selection of 18mm straps in leather, NATO, and rubber, all handcrafted and verified for dimensional tolerance. For a bespoke strap with personal leather selection, the Casati Milano made-to-measure service is available.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and maintenance. A quality vegetable-tanned calf strap worn daily typically lasts 2–4 years. Alligator, thanks to its dense fibre structure, can last over 5 years with proper care. Casati Milano straps come with an 18-month warranty against manufacturing defects.
