Strap for Chronomat 44 Stainless Steel / Blue / Rubber

The lug width of the Breitling Chronomat B01 44 reference AB011011/C789/145S is 22mm. This measurement is taken between the two lug horns and is the key parameter for selecting a compatible strap, whether original Breitling or aftermarket.

The most suitable materials for the Chronomat B01 44 are vegetable-tanned calfskin for everyday wear, wide-grain alligator for formal occasions, and vulcanised rubber for sports or summer use. The lug width is 22mm. A strap with slightly curved ends improves fit against the lug geometry of this particular model.

To replace the strap on the Chronomat B01 44, a fine-tipped spring bar tool is required. The 22mm spring bars are compressed laterally within the holes located on the lug horns. The operation requires no power tools and does not involve the case or movement. It is advisable to work on a soft surface to avoid scratching the caseback or bezel.

Yes. Any 22mm strap with straight or slightly curved ends is compatible with the Chronomat B01 44. Milano Straps offers a selection of handcrafted straps in calfskin, alligator, nylon and rubber, specifically designed for 22mm lug watches, with finishes and thicknesses suited to integrate with the sporty case of this model.

The lifespan of a leather strap depends on the type of hide, frequency of use, and exposure to perspiration and moisture. A quality calfskin strap, with regular use, has an average lifespan of 12 to 24 months. Alligator or vegetable-tanned leather straps tend to last longer, developing a distinctive patina over time. Milano Straps guarantees its straps for 18 months against manufacturing defects.
