Strap for Chronomat B01 42 Stainless Steel - Diamond / White / Rubber

The Breitling Chronomat B01 42, reference AB01346B1A1A1, features a lug width of 22mm. This measurement is standard across the entire Chronomat 42 family and ensures broad compatibility with aftermarket straps.

For the Chronomat B01 42, a vegetable-tanned alligator strap is the most refined choice for formal occasions, whilst box-calf leather offers the most versatile everyday option. For sport or water-adjacent use, a vulcanised rubber strap is the most practical solution. All straps must feature a 22mm attachment width.

The Chronomat B01 42 lugs feature drilled through-holes for the spring bars. Using a fine-tipped spring bar tool, compress the spring on one side, slide out the bar and remove the strap. It is advisable to protect the case with a soft cloth during the operation to prevent micro-scratches on the steel.

Yes. Any strap with a 22mm attachment is technically compatible with the Breitling Chronomat B01 42. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically sourced for this lug width, supplied with spring bars and verified compatibility.

The lifespan of a leather strap depends on the quality of the hide and daily care. A high-quality alligator or calf-leather strap, kept away from water and excessive perspiration and regularly treated with a conditioning cream, will maintain its structural integrity for 3 to 5 years with regular wear. Milano Straps straps include an 18-month manufacturing warranty.
