Strap for Chronomat 44 Rose Gold / Onyx Black / Croco

The lug width of the Breitling Chronomat B01 44 HB0110C1.B968.743P is 22mm. This measurement refers to the internal distance between the two lugs of the case, taken with a digital calliper perpendicular to the spring bar axis. This is the figure required when ordering a compatible strap.

For an 18k rose gold case such as that of the Chronomat B01 44, vegetable-tanned alligator leather in bordeaux, tobacco or midnight blue is the most coherent choice in terms of both material and aesthetic. Shell cordovan offers a refined alternative for those seeking a compact, long-lasting surface. For more dynamic wear, vulcanised rubber provides comfort and moisture resistance.

Changing the strap on a Breitling Chronomat B01 44 requires a standard 22mm spring bar. Using a spring bar tool or a flat-head watch screwdriver, compress the ends of the bar until it releases from the lugs. The operation can be performed at home with the correct tools, or entrusted to a watchmaker or the Casati Milano atelier for a precise result without risk of scratching the rose gold case.

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Chronomat B01 44 HB0110C1.B968.743P. milanostraps.it offers a selection of handcrafted straps in various materials — leather, alligator, cordovan, NATO, rubber — all calibrated to this specification and manufactured to quality standards befitting a case of this calibre.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned alligator strap, kept away from prolonged moisture and treated periodically with appropriate creams, can last between 3 and 7 years whilst retaining its structural and aesthetic integrity. Cordovan, thanks to the density of its fibres, is generally more resistant to daily wear. Casati Milano offers an 18-month guarantee against manufacturing defects on all atelier straps.
