Strap for Chronomat 44 GMT Stainless Steel / Onyx Black / Rubber

The Breitling Chronomat B01 44 AB0420B9.BB56.152S has a lug width of 22 mm. This measurement should be taken internally between the two lugs using a millimetre calliper. The strap typically tapers to 20 mm at the buckle end, creating a proportionate silhouette relative to the 44 mm case.

The most suitable materials for the Chronomat B01 44 are alligator leather with a large grain for formal wear, vegetable-tanned Tuscan calf for those seeking a patina that develops with use, technical nylon NATO for everyday sport use, and vulcanised rubber for high-intensity activities or water exposure. For a black dial with gilt indices, dark tobacco, cognac and dark brown colourways work particularly well.

The Chronomat B01 44 uses standard 22 mm springbars with straight lugs. A thin-tip springbar tool is all that is required: compress both ends of the springbar, slide out the old strap and fit the new one. No professional tools are needed, though working on a soft watchmaker's mat is advisable to avoid scratching the case.

Yes, the Breitling Chronomat B01 44 AB0420B9.BB56.152S accepts any aftermarket strap with a 22 mm lug width and straight ends. milanostraps.it stocks a curated selection of handcrafted 22 mm straps in leather, alligator, NATO and rubber, available both ready to ship and bespoke, with a level of craftsmanship comparable to OEM Breitling straps.

The lifespan of a leather strap depends on leather quality, frequency of use and exposure to perspiration and moisture. A high-grade vegetable-tanned calf strap, with regular use and basic maintenance (conditioning every three to four months, air-drying away from heat sources), will retain its structural integrity and appearance for two to four years. Alligator straps, owing to the density of the hide, tend to last longer when kept dry. milanostraps.it backs its straps with an 18-month warranty against manufacturing defects.
