Strap for Chronomat B01 42 NFL Cleveland Browns / Rouleaux

The lug width of the Breitling Chronomat B01 42 (ref. AB01342B1B6A1) is 22mm. This measurement should be taken with a digital calliper on the inner gap between the two lugs, at the point where the strap inserts into the case.

The most suitable materials for the Chronomat B01 42 are perforated vegetable-tanned calfskin in a rally style, which references the model's aeronautical and motorsport heritage, or Hornback alligator for a more formal register. Vulcanised rubber and ballistic nylon NATO straps are ideal for intensive sporting use. The correct size is 22mm.

To replace the strap on the Chronomat B01 42, use a dedicated spring bar tool or a fine flat-head watchmaker's screwdriver to release the spring bars from the lugs. Standard spring bars have a 1.5mm diameter. Work on a soft surface to avoid scratching the case. The strap width required is 22mm.

Yes. Any strap with a 22mm attachment and standard spring bars is compatible with the Chronomat B01 42. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, calfskin, rubber and NATO specifically in 22mm, crafted from selected materials and available in various lengths to suit all wrist circumferences.

The lifespan of a leather strap depends on the quality of the tanning process, daily use and exposure to perspiration and moisture. A high-quality vegetable-tanned calfskin strap typically lasts between 18 and 36 months with daily wear. Alligator straps, if properly maintained, can exceed 3 to 5 years. Milano Straps provides an 18-month guarantee against manufacturing defects.
