Strap for Chronomat 44

The native lug width of the Breitling Chronomat B01 44 IB011012.B968.375A is 22 mm. This measurement is dictated by the structural proportions of the 44 mm case and ensures correct mechanical and aesthetic balance between the strap and the overall weight and diameter of the watch.

For the steel and rose gold variant, the most coherent materials are alligator leather in tobacco or cognac tones — which visually echo the warmth of the rose gold — or vegetable-tanned calfskin in a matte finish. For a more sporting register, a perforated rally-style strap or a technical rubber version with a deployant clasp maintains consistency with the Chronomat's aeronautical heritage.

The Chronomat B01 44 features standard lugs that accept 22 mm spring bar straps. Replacement is carried out using a flat-blade strap tool or spring bar tool: compress the spring bar laterally, remove the old strap, and fit the new one. It is advisable to place the watch face-down on a soft pad to prevent scratches to the bezel and case. If in doubt, consult a professional watchmaker.

Yes. Any strap with a 22 mm lug width is technically compatible with the Breitling Chronomat B01 44. Milano Straps offers a curated selection of Italian handcrafted straps — in alligator, calfskin, shell cordovan and rubber — made specifically for 22 mm lugs, with finishes and colour palettes designed to complement the chromatic variants of this reference.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. A quality vegetable-tanned calfskin strap worn daily and kept away from excessive moisture and perspiration typically lasts between 18 and 36 months. An alligator or shell cordovan strap, owing to its dense fibre structure, can exceed three years while retaining its form and finish. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
