Strap for Navitimer B01 Chronograph 43 Stainless Steel / Wempe Signature Collection / Bracelet

The Breitling Navitimer AB01387A1C1A1 has a lug width of 22mm. This measurement is taken between the two lower lugs using a millimetre calliper, at the point where the strap meets the case, excluding the outer lug tips. Any strap with a 22mm attachment will be compatible with this reference.

For the Navitimer AB01387A1C1A1 in 43mm stainless steel, the most suitable straps are vegetable-tanned Tuscan calfskin for a heritage aesthetic, shell cordovan for those seeking long-term resilience and patina development, or Mississippi alligator for formal occasions. A brushed stainless steel deployant clasp completes the pairing whilst maintaining visual coherence with the case. For sporting use, a ballistic nylon NATO strap reinforces the watch's aeronautical DNA.

To replace the strap on the Navitimer AB01387A1C1A1, use a spring bar tool or a fine-tipped pin. Compress the spring bar between the two lugs by gently applying leverage with the tool, remove the strap, then insert the new one with the spring bar pre-compressed. Care must be taken to avoid scratching the stainless steel case: it is advisable to protect the lugs with low-tack adhesive tape during the procedure.

Yes, all straps with a standard 22mm attachment are compatible with the Breitling Navitimer AB01387A1C1A1. Milano Straps offers a selection of Italian handcrafted straps in leather, alligator, shell cordovan and technical materials, made using the same artisanal techniques as high-end strap manufacturers, with stainless steel buckle or deployant clasp. The standard length is 120/75mm to suit the majority of wrist sizes.

The lifespan of a leather strap for the Navitimer AB01387A1C1A1 depends on the quality of the tanning, the leather thickness and frequency of use. A quality vegetable-tanned calfskin strap, treated with neutral wax every 3-4 months and kept away from excessive moisture, will retain its characteristics for 2-4 years with daily wear. Shell cordovan, owing to its dense fibrous structure, can exceed 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
