FAQ

What is the lug width of the Breitling Navitimer U17395211A1P2?

The Breitling Navitimer U17395211A1P2 features a lug width of 18mm. This measurement, taken between the two lugs at the point where the strap attaches, is essential for selecting a compatible strap and ensuring a precise fit without lateral play.

What is the best strap for the Breitling Navitimer U17395211A1P2?

For the Navitimer U17395211A1P2 in stainless steel at 35mm, a vegetable-tanned calfskin strap with fine grain offers the most balanced choice: it develops a natural patina over time and suits both formal and everyday wear. Alligator leather elevates the formal profile, while a NATO nylon strap or a vulcanised rubber strap cater to more active use.

How do you change the strap on a Breitling Navitimer U17395211A1P2?

The strap on the Navitimer U17395211A1P2 is secured by spring bars, which can be released using a fine-tipped springbar tool inserted into the inner channel of each lug. It is advisable to work on a soft surface to protect the case from scratches. If in doubt, a watchmaker or the Casati Milano atelier can perform the swap in a matter of minutes.

Are there aftermarket straps compatible with the Breitling Navitimer U17395211A1P2?

Yes. Any strap with an 18mm lug width is technically compatible with the Breitling Navitimer U17395211A1P2. Milano Straps offers a curated range of handcrafted 18mm straps in various materials — leather, rubber, NATO — manufactured with standard spring bars and verified for dimensional compatibility with the Navitimer's lugs.

How long does a leather strap last on a Breitling Navitimer U17395211A1P2?

The lifespan of a leather strap depends on hide quality, tanning method, and daily use. A quality vegetable-tanned calfskin strap, worn regularly but kept away from prolonged moisture exposure, will maintain its structural and aesthetic integrity for 2 to 4 years. Casati Milano straps in alligator or premium calfskin carry an 18-month production defect warranty.
