Strap for Chronomat Automatic 36 Victoria Beckham Stainless Steel / Dove Grey

The Breitling Chronomat 36 A103801A1G1A1 has a lug width of 18mm. This is the internal distance between the two lugs of the case and must be measured with a calliper before purchasing any aftermarket strap.

For the steel Chronomat 36, a fine-grain glossy alligator strap best complements the elegance of the 36mm case. Vegetable-tanned calf leather is ideal for daily wear, developing a natural patina over time. For more active use, vulcanised rubber or ballistic nylon NATO straps preserve the model's technical character. The correct width in all cases is 18mm.

The Chronomat 36 strap is secured with standard 18mm spring bars, removable using a spring bar tool or a thin flat-head screwdriver. No watchmaker is required for this operation. Placing a soft cloth beneath the case during the procedure will protect the steel lugs from scratches.

Yes. Any standard strap with an 18mm attachment is technically compatible with the Breitling Chronomat 36 A103801A1G1A1. Milano Straps offers a curated selection of handcrafted leather, rubber, and fabric straps specifically suited to this lug width, available online or made to measure at the Casati Milano atelier.

Strap longevity depends on the material and frequency of use. A vegetable-tanned calf strap worn daily typically lasts 2 to 4 years with proper care. Shell cordovan, owing to its dense fibre structure, can exceed 5 years. CITES-certified alligator leather, kept away from excessive moisture, retains its structure and finish for many years. Casati Milano provides an 18-month warranty against manufacturing defects on all bespoke straps.
