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

The lug width of the Breitling Chronomat B01 44 CB0110AA.C790.731 is 22mm. This measurement is taken internally between the two case lugs using a millimetre calliper. It is the correct dimension to specify when ordering a compatible aftermarket strap.

For the two-tone steel and rose gold Chronomat B01 44, the most suitable straps are alligator belly or hornback in cognac or tobacco tones, or shell cordovan in bordeaux. These materials complement the warm reflections of the rose gold and suit the substantial 44mm case. A two-tone deployante clasp completes the pairing coherently.

The strap on the Chronomat B01 44 is removed using a spring bar tool inserted between the lug and the strap end. It is advisable to work on a soft surface to avoid scratching the case. The standard 22mm spring bar is compatible with most aftermarket straps. If in doubt, a watchmaker or the Casati Milano atelier can perform the swap in a matter of minutes.

Yes, the Breitling Chronomat B01 44 CB0110AA.C790.731 uses standard 22mm spring bars, which are compatible with the vast majority of quality aftermarket straps. Milano Straps offers a selection of Italian handcrafted 22mm straps in various leathers and materials, with customisable taper and buckle or deployante clasp options.

The lifespan of a leather strap depends on the material and conditions of use. A quality alligator strap with vegetable tanning can last between 3 and 6 years with regular wear if kept away from excessive perspiration and prolonged exposure to rain. Shell cordovan, owing to the density of its fibres, tends to last longer. Periodic conditioning with appropriate creams significantly extends the strap's service life.
