Strap for Chronomat 44 Rose Gold / Onyx Black / Rubber

The official lug width of the Breitling Chronomat B01 44 HB011012.B968.153S is 22mm. Before purchasing an aftermarket strap, it is advisable to verify the actual measurement with a digital calliper, as manufacturing tolerances may place the real figure between 21.8mm and 22.2mm.

For an 18-carat rose gold case, the most suitable materials are vegetable-tanned alligator leather (cognac, tobacco or bordeaux), shell cordovan which develops a patina with vinous reflections complementary to rose gold, and boxy tannage calf leather with a polished finish. For sporting use, grained vulcanised rubber maintains the visual proportions of the original bracelet.

The Chronomat B01 44 uses standard 22mm spring bars. Replacement requires a fine-tipped spring bar tool to release the bars from the lugs. The short, angled lugs of the Chronomat require a 90° tipped tool to access the spring bar holes comfortably without scratching the rose gold case.

Yes. Aftermarket straps with straight ends at 22mm are compatible with the Chronomat B01 44. It is important to check that the thickness at the attachment end is appropriate for the lug curvature. Milano Straps produces handcrafted straps specifically calibrated for Breitling lugs, available in the 22mm collection.

Longevity depends on leather quality, usage and maintenance. A high-quality alligator or shell cordovan strap in vegetable tan, worn with care, can last between 3 and 6 years whilst retaining structural integrity and patina. Frequent exposure to water and perspiration is the primary cause of accelerated deterioration: for intensive sporting use, alternating with a rubber strap is recommended.
