Strap for Navitimer B02 Chronograph 41 Cosmonaute Stainless Steel - Platinum / Black / Alligator - Folding

The lug width of the Breitling Navitimer PB02301A1B1P1 is 22mm. This measurement is integral to the case design and must be matched precisely when selecting a replacement strap to ensure correct and secure fitment.

Given the platinum and stainless steel case of the Navitimer PB02301A1B1P1, a matte or semi-gloss belly alligator strap is the most fitting choice for the watch's calibre. Alternatively, Tuscan vegetable-tanned calf leather offers a sportier aesthetic with a personal patina developing over time. For active use, vulcanised rubber with a technical texture is the most practical option.

The strap on the Navitimer PB02301A1B1P1 is replaced by removing the two spring bars securing it to the case lugs. A double-ended springbar tool, inserted into the lug hole or between the lug and strap, compresses the bar and releases the strap. The procedure takes only a few minutes but requires care to avoid scratching the case.

Yes. Any strap with a 22mm attachment width and standard length (approximately 120mm for the long piece and 75mm for the short piece) is technically compatible with the Navitimer PB02301A1B1P1. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials, with bespoke options available through Casati Milano.

The lifespan of a leather strap depends on the material and conditions of use. A quality vegetable-tanned alligator strap, properly cared for (avoiding prolonged exposure to water, perspiration, and direct sunlight), typically lasts between two and five years with daily wear. Tuscan calf leather has a comparable lifespan but develops a patina more rapidly. Rotating between two straps significantly extends the life of each.
