Strap for Chronomat 44

The lug width of the Breitling Chronomat B01 44, reference IB011012B957435X, is 22 mm. This measurement is standard across the entire Chronomat 44 line and is determined by the proportions of the 44 mm bi-material rose gold and stainless steel case.

For the Chronomat B01 44, hornback alligator straps are recommended to complement the textured rider tabs bezel, or vegetable-tanned Tuscan calf leather for a natural patina that develops character over time. For sporting use, vulcanised rubber maintains the chronograph's original instrumental vocation.

The strap on the Chronomat B01 44 is replaced using standard 22 mm spring bars. A springbar tool is sufficient to compress and release the bars from the lugs, remove the old strap and fit the new one. Care should be taken to avoid scratching the bi-metal rose gold and steel case.

Yes, the Breitling Chronomat B01 44 accepts any aftermarket strap with a 22 mm lug width and standard spring bars. Milano Straps offers a curated selection of handcrafted 22 mm straps in leather, rubber and technical materials specifically suited to this reference.

The lifespan of a leather strap depends on hide quality and maintenance. A high-grade vegetable-tanned strap, regularly conditioned and protected from excessive perspiration and water exposure, can last between two and five years with daily wear. Cordovan and alligator leathers tend to outlast standard calf due to the density of their fibre structure.
