Strap for Chronomat 44 Stainless Steel / Patrouille de France / Rubber

The lug width of the Breitling Chronomat B01 44 reference AB01109E.C886.224S is 22 mm. This measurement is taken between the two case lugs at the point where the strap attaches and determines the correct width for any aftermarket strap purchase.

The most suitable straps for the Chronomat B01 44 are: perforated rally calf leather for a vintage aeronautical aesthetic, matte alligator for formal occasions, vulcanised rubber for intensive sporting use, and ballistic nylon NATO for maximum everyday versatility. The ideal choice depends on the dial colour and intended context.

The strap is removed using a fine-tipped spring bar tool. Simply compress the spring bar between the case lugs and slide the strap out. It is advisable to work on a soft surface to avoid scratching the case, and to ensure that replacement spring bars are 22 mm wide with a compatible diameter.

Yes, any strap with a lug width of 22 mm is technically compatible with the Chronomat B01 44. Milano Straps offers a selection of handcrafted leather, alligator, rubber and NATO straps specifically available in the 22mm size, designed to fit the geometry of Breitling lugs.

A quality leather strap on a sports chronograph such as the Chronomat B01 44 typically lasts between one and three years with daily wear, depending on perspiration, water exposure and maintenance. Vegetable-tanned leathers develop a distinguished patina over time but require more care than treated leathers. Milano Straps straps are covered by an 18-month warranty against manufacturing defects.
