Strap for Chronomat 44 Rose Gold / Diamond / Pearl Diamond / Croco

The lug width of the Breitling Chronomat B01 44 reference HB0110AE.A698.739P is 22mm. This measurement is taken between the two lugs on the case, at the 12 o'clock side, using a millimetre ruler inserted into the strap slot. This is slightly wider than the average in the sport-luxury segment and requires straps specifically manufactured for 22mm.

For the Chronomat B01 44 in rose gold, the materials that best complement the case are alligator leather with Hornback or Porosus grain in warm tones (cognac, tobacco, bordeaux) and Tuscan calf leather in vegetable tan with a pull-up finish. Both develop a patina over time, harmonising with the natural ageing of rose gold. Vulcanised technical rubber is recommended for sporting use, while a deployant clasp provides security and visual coherence with the case.

The strap on the Chronomat B01 44 is replaced using a springbar tool inserted into the lug channel to compress the spring bar. The operation is fully reversible and does not require a watchmaker. We recommend placing the watch on a cushioned holder to protect the rose gold case from accidental scratches during the strap change.

Yes.

The lifespan of a leather strap depends on the quality of the raw material, the craftsmanship and the conditions of use. A high-quality Tuscan calf or alligator strap, with daily wear and ordinary care (avoiding prolonged exposure to water and perspiration), will maintain structural and aesthetic integrity for 2 to 4 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
