Strap for Navitimer B01 Chronograph 43 Stainless Steel - Red Gold / Aeromexico

The Breitling Navitimer UB01381A1C1P1 has a lug width of 22 mm. This measurement is consistent with the 43 mm case diameter and is a standard size among professional chronographs of this format.

Given the two-tone red gold and stainless steel case of the Navitimer UB01381A1C1P1, a dark tobacco or cognac alligator leather strap is the most harmonious pairing. Shell cordovan and vegetable-tanned calfskin are equally well-suited options, whether with a pin buckle or a deployant clasp.

The Navitimer strap is removed using a spring bar tool to compress and release the spring bars connecting the strap to the case lugs. The operation takes approximately two minutes and can be performed at home without risk of scratching the case, provided the correct tool is used.

Yes. The 22 mm lug width is a widely used standard, making it compatible with any aftermarket strap of the same size. Milano Straps offers a curated selection of handcrafted 22 mm straps in various materials and colours, all compatible with the Navitimer UB01381A1C1P1.

The lifespan of a leather strap depends on material quality and daily use. A well-crafted alligator or shell cordovan strap with vegetable tanning can last between three and six years with standard care — avoiding prolonged exposure to water and perspiration. Rotating between multiple straps significantly extends the life of each one.
