Strap for Chronomat 44 White Gold / Diamond / Gray Pearl / Bracelet

The lug width of the Breitling Chronomat B01 44 reference JB0110AE.G685.375J is 22mm. This measurement is taken with a calliper between the two lugs at the point closest to the case. Any standard 22mm strap is compatible with this reference.

For a 44mm white gold case, a vegetable-tanned alligator strap is the most coherent choice: the natural grain and leather sheen complement the precious metal beautifully. Alternatively, polished box-calf offers a formal option, while vulcanised rubber preserves the Chronomat's sporting heritage.

Strap replacement requires a fine-tipped spring bar tool. The 22mm spring bars are released by pressing the tool into the lug slot. Work on a soft surface to protect the white gold case from scratches. Alternatively, a watchmaker or our Casati Milano atelier can perform the swap by appointment.

Yes. Any aftermarket strap with a 22mm lug width and appropriate end-piece thickness is compatible. Milano Straps offers handcrafted leather, rubber and nylon straps specifically sized at 22mm, finished to a standard befitting a watch of this calibre.

Longevity depends on the material and conditions of use. A quality alligator or vegetable-tanned calf strap, conditioned every two to three months and kept away from prolonged moisture, can last between three and five years with daily wear. Milano Straps products carry an 18-month warranty against manufacturing defects.
