Strap for Chronomat 44 GMT Stainless Steel / Metallica Brown / Bracelet

The lug width of the Breitling Chronomat B01 44 AB042011.Q589.375A is 22mm. The lugs feature a curved profile (curved end), so it is essential to use straps with specifically shaped ends to ensure a proper fit against the case.

For the Chronomat B01 44, an alligator hornback strap in black or midnight blue enhances the instrument-oriented character of the dial. Alternatively, a vegetable-tanned calfskin strap in tan or havana develops a distinctive patina over time. For sporting or water-related use, vulcanised rubber with a ribbed texture is the most functional choice. All straps must feature curved ends at 22mm.

To replace the strap on the Chronomat B01 44, the spring bars securing the strap to the case lugs must be removed. Use a fine-tipped spring bar tool inserted into the lateral hole of the lug to compress the spring and slide the bar out. It is advisable to protect the case with a soft cloth during the operation to avoid scratching the steel finish.
