Strap for Chronomat 44 Stainless Steel / Blue / Calf

The lug width of the Breitling Chronomat B01 44 AB011011/C789/105X is 22mm. This is the standard measurement taken between the two lugs of the case, best verified using a digital calliper with the case resting on a flat surface, measuring internally at the level of the caseback.

For the Chronomat B01 44, the most suitable materials are square-scale alligator in black or navy blue for a formal-sport aesthetic, full-grain vegetable-tanned calf leather for those seeking character and patina over time, and vulcanised rubber for intensive use. The correct width is 22mm with a 20mm tail.

The strap on the Breitling Chronomat B01 44 is replaced using a fine-tipped or flat spring bar tool. The Chronomat's lugs have a curved integrated profile: lever gently against the end of the spring bar towards the inside of the lug. It is advisable to rest the case on a non-scratch watch mat and proceed carefully to avoid marking any polished surfaces.

The lifespan of a leather strap depends on leather quality, frequency of use, and exposure to perspiration and moisture. A quality artisan vegetable-tanned calf strap, regularly conditioned with appropriate products and not continuously exposed to humidity, can last between 2 and 5 years. Alligator leather, owing to its dense natural fibre structure, generally offers greater longevity.
