Strap for Chronomat 44 Stainless Steel / Pearl Roman / Bracelet

The lug width of the Breitling Chronomat B01 44 AB011012.A691.375A is 22mm. This measurement should be taken with a digital calliper inside the lugs, at the narrowest point where the strap attaches. Fitting a strap of a smaller width would result in lateral play and could compromise the security of the spring bars.

For the Chronomat B01 44, a perforated rally strap in vegetable-tanned calf leather is the most coherent choice given the model's racing heritage. Alternatively, a padded alligator strap in midnight blue or tobacco brown complements the dial without undermining the sporting character of the watch. For intensive or aquatic use, a 22mm vulcanised rubber strap is the most practical option.

To replace the strap on the Chronomat B01 44, you will need a fine-tipped or lever-type spring bar tool. Insert the tool into the slot of the spring bar, compress the bar inward and slide the strap free from the lug. Repeat on the other side. The new 22mm strap is fitted by compressing the spring bars before inserting them into the lugs. No watchmaker's intervention is required.

Yes. Any strap with a 22mm lug width is compatible with the Breitling Chronomat B01 44. Milano Straps offers a selection of handcrafted straps in alligator, calf leather, NATO and rubber, all available in 22mm. It is also worth checking the overall strap length (standard 75/115mm, or 70/115mm for slimmer wrists) and the preferred buckle or deployant clasp type.

The lifespan of a leather strap depends on material quality, frequency of wear, and exposure to perspiration and moisture. A quality handcrafted alligator or vegetable-tanned calf strap, worn in rotation with other straps, can last between two and five years. Avoiding direct water contact and occasionally applying a leather conditioner will significantly extend its life. Milano Straps provides an 18-month warranty against manufacturing defects.
