Strap for Chronomat 41

The lug width of the Breitling Chronomat B01 41 CB014012G713428X is 20 mm. This measurement is taken with a digital calliper between the two inner lugs of the case and is the key parameter for selecting any compatible aftermarket strap.

For the two-tone steel and rose gold variant, the most coherent options are vegetable-tanned alligator in cognac or burgundy tones, which complement the warm reflections of the rose gold, and grained calf leather in tobacco or dark brown. For intensive sporting use, a vulcanised rubber strap with a rose gold PVD buckle maintains the chromatic harmony of the case.

Strap removal is performed using a fine-tipped spring bar tool inserted into the lug slot to compress the spring bars. The Chronomat B01 41 lugs curve slightly downward: it is advisable to work on a soft surface to protect the bezel and case. For a first-time replacement, it is recommended to consult a qualified watchmaker or the Casati Milano atelier.

Yes. Any strap with a standard 20 mm attachment is technically compatible. milanostraps.it offers a selection of handcrafted 20 mm straps in leather, rubber and nylon specifically curated for geometry and finish. For a bespoke result, the Casati Milano atelier produces custom straps with personal leather selection.

Longevity depends on leather type, maintenance and frequency of use. A quality alligator strap with vegetable tanning, kept away from prolonged perspiration and moisture, can last between 3 and 5 years with regular wear. Calf leather typically lasts 2 to 3 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
