Frequently asked questions

What is the lug width of the Breitling Chronomat B01 44 CB0110121B1P1?

The Breitling Chronomat B01 44 CB0110121B1P1 has a lug width of 22 mm. This measurement refers to the internal distance between the two lugs where the strap is fitted. It is advisable to verify this with a vernier calliper before purchasing an aftermarket strap.

What is the best strap for the Breitling Chronomat B01 44 CB0110121B1P1?

For the two-tone rose gold and stainless steel case of the CB0110121B1P1, straps in vegetable-tanned alligator in cognac, bordeaux or midnight blue are the most coherent choice aesthetically and qualitatively. Shell cordovan is recommended for those who appreciate a natural patina that develops over time. For more sporting use, vulcanised rubber or technical nylon NATO straps are functionally sound options.

How do you change the strap on a Breitling Chronomat B01 44?

To replace the strap on the Breitling Chronomat B01 44, you will need a spring bar tool with a 1 mm or 1.5 mm tip. Insert the tip into the spring bar slot on the lug, compress the spring bar and slide the strap free. The Chronomat uses standard 22 mm spring bars compatible with most tools available on the market. It is advisable to work on a soft surface to avoid scratching the rose gold case.

Are there aftermarket straps compatible with the Breitling Chronomat B01 44 CB0110121B1P1?

Yes, the Breitling Chronomat B01 44 CB0110121B1P1 features a standard 22 mm lug width that accepts the majority of aftermarket straps in this size. It is important to ensure the strap has a straight (not curved) end and that the taper dimensions are 22/20 mm or 22/18 mm depending on the buckle used. Casati Milano produces bespoke straps compatible with this model, with leather selection available in the atelier.

How long does a leather strap last on a Breitling Chronomat B01 44?

The lifespan of a leather strap depends on the material, the tanning method and daily use. A quality vegetable-tanned alligator strap, properly cared for and kept away from prolonged moisture exposure, can last between 3 and 6 years while retaining a distinguished appearance. Shell cordovan straps are generally more resistant to moisture and develop a characteristic patina over time. Casati Milano offers an 18-month guarantee on manufacturing defects on all their straps.
