Strap for Chronomat 44 Stainless Steel / Blue / Bracelet

The lug width of the Breitling Chronomat B01 44 AB011012.C788.375A is 22mm, measured internally between the two parallel lugs at the strap attachment point. This is the correct measurement to specify when ordering a compatible strap.

For the Chronomat B01 44 with its 44mm case, the most suitable straps are Hornback alligator for a formal-sport aesthetic, vegetable-tanned calf leather for a daily-wear option that develops a natural patina, or FKM rubber for technical and marine environments. In all cases, the correct width is 22mm at the lugs tapering to 20mm at the buckle.

The strap on the Chronomat B01 44 is secured by standard 22mm spring bars. To replace it, use a spring bar tool to compress the spring bar on one side, slide the strap out, and fit the new one. No specialist tools are required, though care should be taken to avoid scratching the steel lugs during the process.

Yes, any aftermarket strap with standard 22mm spring bars is technically compatible with the Breitling Chronomat B01 44 AB011012.C788.375A. Milano Straps offers handcrafted Italian leather, NATO and rubber straps specifically selected for this lug width, with bespoke options available through the Casati Milano atelier.

The lifespan of a leather strap depends on hide quality, care and frequency of use. A handcrafted alligator or vegetable-tanned calf leather strap, kept away from prolonged water exposure and treated periodically with a natural conditioner, can last between three and six years with daily wear. Using a deployant clasp reduces mechanical stress on the strap holes and considerably extends the service life of the strap.
