Strap for Chronomat 44 Stainless Steel / Rose Gold / Diamond / Metallica Blue / Bracelet

The Breitling Chronomat B01 44 CB011053.C790.375C has a lug width of 22mm. This measurement is taken with a calliper between the two lugs at the lower part of the case, where the strap is inserted. The standard taper towards the buckle is typically 20mm.

For this two-tone stainless steel and rose gold version, the most suitable straps are alligator in cognac or tobacco tones — which complement the bi-colour finish — or vegetable-tanned calfskin for a more sporting register. Vulcanised rubber is preferable for daily wear and humid environments. A deployant clasp in steel or rose gold PVD completes any pairing.

Strap replacement is carried out using a fine-tipped spring bar tool, carefully levering the spring bar that connects the strap to the lug. It is advisable to protect the case with a soft cloth during the operation. The 22mm lug is compatible with standard 1.5mm diameter spring bars. If in doubt, consult a qualified watchmaker.

Yes. Any aftermarket strap with a 22mm lug width is compatible with the Chronomat B01 44 CB011053.C790.375C. Milano Straps offers a selection of handcrafted 22mm straps in various materials — leather, alligator, NATO, rubber — made specifically for cases of this size.

The lifespan of a leather strap depends on the material, craftsmanship and usage. A quality vegetable-tanned calfskin strap worn daily typically lasts 18–24 months. A well-maintained alligator strap can last 4–5 years. Milano Straps products carry an 18-month guarantee against manufacturing defects.
