Strap for Chronomat 44 Stainless Steel / Black / Bracelet

The lug width of the Breitling Chronomat B01 44 AB011011/B967/375A is 22mm. This measurement is taken internally between the two lugs at the point where the strap attaches to the case, and is the key specification when selecting a compatible replacement strap.

The Chronomat B01 44 pairs well with vegetable-tanned calfskin for daily wear, with pronounced-grain alligator for more formal occasions, with vulcanised rubber for sporting or marine environments, and with a 22mm NATO strap to reference the model's military heritage. The ideal choice depends on context and personal aesthetic.

To replace the strap on the Chronomat B01 44, use a double-ended springbar tool. Insert the tip into the dedicated slot on the lug, compress the springbars and slide the strap free. Care is required to avoid scratching the case surfaces. Alternatively, a watchmaker or the Casati Milano atelier can perform the strap change without risk.

Yes, any strap with a 22mm lug width is technically compatible with the Breitling Chronomat B01 44. MilanoStraps offers a curated selection of handcrafted straps in various leathers and materials, designed to integrate with the original lug geometry of the Chronomat without any modification.

The longevity of a leather strap depends on the quality of the hide, level of care and frequency of use. A quality vegetable-tanned calfskin strap used daily, with regular maintenance, retains its structural and aesthetic integrity for 2–4 years. Alligator or shell cordovan straps, properly cared for, can exceed 5 years. MilanoStraps provides an 18-month warranty against manufacturing defects.
