Strap for Navitimer B01 Chronograph 43 Stainless Steel / Purple / Cortin

The lug width of the Breitling Navitimer AB01385C1Q1A1 is 22 mm. This measurement is consistent across all serial production of this reference and should be taken internally between the two lugs using a digital calliper or a millimetre ruler placed directly against the case.

For the steel 43 mm Navitimer AB01385C1Q1A1, the most appropriate options are: smooth-belly alligator leather for formal wear, vegetable-tanned Tuscan calf for a characterful patina, NATO fabric for an authentic aeronautical aesthetic, and vulcanised rubber for active sport use. The final choice depends on chromatic pairing and intended context.

The strap on the Navitimer AB01385C1Q1A1 is removed using a springbar tool or a thin flathead screwdriver: compress the springbar connecting the strap to the lugs and slide it out laterally. Care must be taken to avoid scratching the case. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Yes. Any strap with a standard 22 mm attachment is compatible with the Navitimer AB01385C1Q1A1. Milano Straps offers a wide selection of 22 mm straps in leather, rubber and fabric, handcrafted in Italy, fully compatible with this reference without the need for adapters.

Longevity depends on the material, frequency of use and maintenance. A quality vegetable-tanned leather strap, kept away from excessive water and perspiration and periodically treated with leather conditioner, can last between 2 and 5 years. Alligator models with robust stitching and quality hardware tend to outlast standard bovine leather straps.
