FAQ

What is the lug width of the Breitling Navitimer RB01395A1B1P1?

The lug width of the Breitling Navitimer RB01395A1B1P1 is 14mm. This measurement should be taken with a calliper at the narrowest point between the lugs, where the strap fits. Respecting this specification is essential to ensure correct fitment and eliminate lateral play.

What is the best strap for the Navitimer RB01395A1B1P1 in red gold?

For an 18kt red gold case, alligator straps in bordeaux or cognac, vegetable-tanned, offer the most coherent chromatic and tactile pairing. Alternatively, dark brown calf leather or shell cordovan in mid-tan provide understated elegance without sacrificing depth. The lug width is 14mm, with a recommended taper to 12mm at the buckle end.

How do you change the strap on a Breitling Navitimer?

The Navitimer strap is removed using a flat-tipped springbar tool. Apply gentle lever pressure to the springbars securing the strap to the lugs, taking care not to scratch the red gold case. It is advisable to work on a soft surface and, if in doubt, to entrust the operation to a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Navitimer RB01395A1B1P1?

Yes. Any 14mm strap with slightly curved ends is compatible with the Navitimer RB01395A1B1P1. Milanostraps.it offers a curated selection of handcrafted 14mm straps in alligator, calf leather, shell cordovan and other fine materials, available with a buckle or deployant clasp in various metal finishes.

How long does a leather strap last on a Breitling Navitimer?

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned alligator strap, properly nourished with leather cream and rotated with other straps, can last between 3 and 5 years while retaining a presentable appearance. Prolonged exposure to perspiration and moisture is the primary cause of deterioration; it is advisable to dry the strap after intensive use.
