Strap for Chronomat 44

The lug width of the Breitling Chronomat B01 44 IB011012A693375A is 22mm. This measurement is taken by inserting a millimetre ruler between the two lugs on the inner side of the case, parallel to the bezel. This is the standard lug width across the entire Chronomat 44 family.

For the mother-of-pearl dial and two-tone rose gold/steel case, vegetable-tanned alligator leather in tobacco, cognac or chocolate brown tones is the most aesthetically coherent choice. For sportier use, a NATO or technical rubber strap honours the watch's aeronautical origins. A rose gold deployant clasp completes the pairing with the two-tone case.

The strap on the Breitling Chronomat B01 44 is replaced using standard 22mm springbars. A springbar tool is required to release the bars from the lugs and slide out the strap. Care should be taken to avoid scratching the two-tone case: a tool with a plastic or nylon-coated tip is strongly recommended.

A quality leather strap — alligator or calf in vegetable tanning — fitted to a Breitling Chronomat B01 44 typically lasts between 2 and 4 years with daily wear, depending on conditions of use. Prolonged exposure to perspiration, water and UV light accelerates wear. Periodic conditioning with a leather cream significantly extends the strap's service life.
