Strap for Chronomat 44 Stainless Steel / Diamond / Sierra Silver / Bracelet

The lug width of the Breitling Chronomat B01 44 reference AB0110AA.G684.375A is 22 mm. This measurement is taken between the inner lugs using a digital calliper and determines the correct strap width for any aftermarket replacement.

The most suitable materials for the Chronomat B01 44 are Mississippi alligator leather for formal occasions, vegetable-tanned calfskin for everyday wear, and vulcanised rubber or nylon NATO straps for sporting use. The optimal choice depends on the dial colour and intended use.

To replace the strap, use a fine-tipped spring bar tool to release the 22 mm spring bars from the lugs. Work on a soft surface to protect the case and bezel. The rider tabs do not obstruct the operation, but care should be taken when positioning the tool to avoid scratching the lug area.

Yes. Any strap with a 22 mm attachment and standard spring bars is technically compatible. Milano Straps offers a curated range of handcrafted 22 mm straps in leather, alligator, calfskin and technical materials, all compatible with the Chronomat B01 44.

A quality leather strap on a 44 mm sports watch typically lasts between 18 and 36 months with daily use, depending on exposure to perspiration, water and direct sunlight. Vegetable-tanned straps develop a personal patina over time and can last longer when treated periodically with neutral wax and kept dry after use.
