Strap for Chronomat 38 SleekT Stainless Steel / Diamond / MOP / Bracelet

The lug width of the Breitling Chronomat 38 A1331053/A776/385A is 20mm. This measurement is taken between the inner walls of the case lugs and determines compatibility with all standard 20mm aftermarket straps.

The choice depends on intended use and personal style. For an elegant aesthetic, a vegetable-tanned alligator or shell cordovan strap complements the technical character of the case. For versatile daily wear, smooth full-grain calf leather in cognac or black is ideal. For a tool-watch look, a nylon NATO strap references the Chronomat's aviation heritage.

To replace the strap or bracelet on the Chronomat 38, a fine-tipped spring bar tool is required. The 20mm spring bars are released by applying pressure in the dedicated notches on the lugs. Always work on a soft surface to avoid scratching the case. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a standard 20mm attachment is compatible with this model. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically sourced for the 20mm lug width, with finishes and materials comparable or superior to the original Breitling.

The lifespan of a leather strap depends on the material, tanning method and use. A quality vegetable-tanned alligator strap, with regular but careful use, typically lasts 2–4 years. Shell cordovan, owing to its dense and compact structure, can exceed 5 years. Exposure to water, excessive perspiration and UV rays accelerates deterioration. Milano Straps straps carry an 18-month guarantee against manufacturing defects.
