Strap for Chronomat 44 Rose Gold / Onyx Black / Bracelet

The native lug width of the Breitling Chronomat B01 44, reference HB0110C1.B968.375H, is 22mm. This measurement is taken between the two horizontal lugs of the 18kt rose gold case and should be verified with a digital calliper before ordering any aftermarket strap.

For an 18kt rose gold case, the most coherent materials are lacquered alligator in tobacco brown or cognac tones, vegetable-tanned box calf that develops a personal patina over time, and nylon NATO for a nod to the model's aviator origins. A rose gold deployante clasp completes the metallic pairing impeccably.

The Chronomat B01 44 uses a standard 22mm spring bar system. A spring bar tool or fork-tip screwdriver is sufficient: compress the spring bar within the lug, slide out the original strap and insert the new one. Take care not to scratch the rose gold lugs; it is advisable to protect the case with low-tack masking tape during the process.

Yes. Any strap with a 22mm attachment and standard length (75mm+115mm or 80mm+120mm) is technically compatible. Milano Straps offers handcrafted straps in alligator, calf and other premium materials made to fit this model, with buckle or deployante options also available in rose gold plating for a consistent metallic pairing.

Longevity depends on the type of leather and frequency of use. A vegetable-tanned calf strap, properly maintained, typically lasts 18 to 36 months with daily wear; quality alligator, owing to the compact grain structure, can exceed three years while retaining its original profile. Exposure to water, perspiration and UV light accelerates deterioration: immersion should be avoided and the leather treated periodically with silicone-free leather cream.
