Strap for Chronomat 28 Stainless Steel - Red Gold / MOP

The Breitling Chronomat 28 U72310531A1U1 features a lug width of 14mm. This is the internal distance between the two lugs of the case, which should be measured with a digital calliper before purchasing an aftermarket strap.

For this two-tone stainless steel and rose gold model with a mother-of-pearl dial, the most suitable straps are hornback alligator in bordeaux or cognac tones, or vegetable-tanned smooth calf leather in warm hues. A deployant clasp in steel or rose gold PVD is the most coherent closure for the Chronomat's instrumental aesthetic.

The strap is removed using a fine-tipped spring bar tool or a flat watchmaker's screwdriver inserted into the spring bar housing between the lug and the strap. Given the compact 14mm size, precision tools are strongly recommended to avoid scratching the rose gold and stainless steel case.

Yes. Any strap with a 14mm lug width and straight or slightly tapered end is compatible. Milano Straps offers a curated selection of Italian handcrafted 14mm straps in leather, alligator and technical materials, available with buckle or deployant clasp.

Lifespan depends on the material and usage. A quality alligator strap, with periodic conditioning, typically lasts 3–5 years. Vegetable-tanned calf leather develops patina over time and can last even longer, provided it is not regularly exposed to water or perspiration. Casati Milano offers an 18-month warranty against manufacturing defects.
