Strap for Chronomat 44 Stainless Steel / Diamond / Blackeye Blue / Croco

The Breitling Chronomat B01 44 AB0110AA.C789.731P features a 22mm lug width. This measurement is standard across the Chronomat 44 family and allows compatibility with a broad range of aftermarket straps.

For the 44mm stainless steel Chronomat B01 44, we recommend a hornback alligator strap for formal occasions, or a calf leather strap with contrast stitching for everyday sportswear. A butterfly deployant clasp ensures both security and wrist comfort.

The Chronomat B01 44 uses standard 22mm spring bars. To replace the strap, use a spring bar tool or lug lever to compress and remove the spring bar from the lug slot, slide out the old strap and fit the new one. The process is straightforward and does not affect the case.

Yes, the 22mm lug width of the Chronomat B01 44 is widely supported by the aftermarket. Milano Straps crafts bespoke leather, rubber and textile straps specifically compatible with this reference, with customisable finishes and stitching.

The longevity of a leather strap depends on leather quality and daily use. A vegetable-tanned or alligator strap, properly maintained, will retain its shape and colour for 3 to 5 years of daily wear. Prolonged exposure to perspiration and water accelerates wear; rubber or NATO straps are recommended for sport use.
