Strap for Chronomat 44

The lug width of the Breitling Chronomat B01 44 IB011012A693435X is 22 mm. This measurement is consistent across the entire Chronomat B01 44 family, regardless of case finish or original bracelet type. When replacing the strap, it is essential to respect this measurement to preserve the integrity of the lugs and spring bars.

For a two-tone steel and rose gold Chronomat B01 44 with a mother-of-pearl dial, an alligator leather strap in tobacco or dark brown is the most coherent choice given the richness of the case. Alternatively, a vegetable-tanned Barenia calf leather in caramel will develop a patina that harmonises naturally with the rose gold over time. For sporting use, an FKM rubber strap maintains the tool watch character of the model.

To replace the strap on the Breitling Chronomat B01 44, a fine-tipped or fork-style spring bar tool of 1.5 mm is required. The spring bars are released by gently levering into the inner groove of the lugs. Care must be taken not to scratch the polished finish of the steel or rose gold lugs. If in doubt, it is advisable to consult a watchmaker or use the fitting services available through milanostraps.it.
