Strap for Navitimer 1 35 Automatic Stainless Steel / Red Gold / MOP / Bracelet

The Breitling Navitimer U17395211A1U1 features a 35mm case with a lug width of 18mm. This measurement is essential when selecting a replacement strap: any standard 18mm strap with straight ends will be physically compatible with this reference.

For the Navitimer U17395211A1U1 with its 35mm case, a matte alligator strap or a vegetable-tanned calfskin strap are the most coherent choices aesthetically. Calfskin develops a natural patina over time, while alligator offers superior longevity and a formal bearing. For daily or active use, a vulcanised rubber strap is a sound functional alternative.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the dedicated hole or between the lug and the strap end, compress the spring bar and slide the strap free. The operation is fully reversible and does not require Breitling service centre intervention. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any 18mm strap with straight ends is physically compatible with the Navitimer U17395211A1U1. Milano Straps offers a curated selection of handcrafted straps in various materials — alligator, calfskin, rubber and NATO — designed to complement the proportions of the 35mm case without disrupting its visual balance.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap typically lasts between two and four years with daily use. Alligator, owing to the density of its scale structure, offers greater resistance. Casati Milano straps carry an 18-month warranty against manufacturing defects.
