Strap for Chronomat 41

The lug width of the Breitling Chronomat B01 41 CB014012A722431X is 20mm. This measurement is taken between the case lugs using a digital calliper and determines the correct strap width to purchase. Milano Straps' 20mm compatible straps are designed to fit correctly within the lug geometry of this reference.

For the bicolour Chronomat B01 41 in steel and rose gold, the most suitable materials are dark tabac or tête de nègre alligator, bordeaux shell cordovan, and black rubber for sporting use. Vegetable-tanned alligator develops a patina over time that complements the enduring aesthetic of the B01 calibre. A rose gold or pvd gold deployant clasp completes the pairing with chromatic coherence.

Changing the strap on the Chronomat B01 41 requires a quality spring bar tool with a 1.0–1.2mm tip. The 20mm spring bars are removed by leveraging the notch inside each lug. We recommend working on a soft surface to protect the case and rose gold finishes. If in doubt, Casati Milano's service includes professional strap fitting at no additional cost.

Yes, the Chronomat B01 41 accepts any aftermarket strap in 20mm with straight or slightly curved ends compatible with the lug geometry. Milano Straps offers a selection of 20mm straps in leather, rubber, and nylon, handcrafted and compatible with this reference. The Casati Milano bespoke service also allows you to commission a made-to-measure strap with leather chosen personally in the atelier.

The lifespan of a leather strap depends on the material, care, and frequency of use. A quality vegetable-tanned alligator strap, worn in rotation with other straps, can last between 3 and 7 years while retaining a fine appearance. Shell cordovan is even more durable thanks to the density of its fibres. All Milano Straps straps carry an 18-month warranty against manufacturing defects. Avoiding prolonged contact with water and perspiration significantly extends strap life.
