Frequently asked questions

What is the lug width of the Breitling Navitimer A17395211A1P5?

The Breitling Navitimer A17395211A1P5 has an 18mm lug width. This measurement should be taken at the base of the lugs using a digital calliper, between the two spring bar holes, to ensure an accurate strap replacement without play.

What is the best strap for the Breitling Navitimer A17395211A1P5?

Given the 35mm case diameter and the instrument-oriented character of the Navitimer, an 18mm alligator strap with vegetable tanning or a smooth calf leather strap is the most coherent choice. For a sportier look, a woven nylon NATO strap recalls the model's aeronautical heritage. A steel deployant clasp complements any leather pairing.

How do I change the strap on the Breitling Navitimer A17395211A1P5?

The strap is replaced using a spring bar tool to release the spring bars from the lugs. Rest the case on a soft surface to avoid scratching the steel. Original Breitling 18mm spring bars can be reused if in good condition; otherwise, it is advisable to replace them together with the strap.

Are there aftermarket straps compatible with the Breitling Navitimer A17395211A1P5?

Yes, all 18mm straps with a straight or slightly tapered end are compatible with the Navitimer A17395211A1P5. Milanostraps.it offers a curated selection of handcrafted 18mm straps in leather, rubber and nylon, finished to complement the aesthetics of this model.

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

The lifespan of a leather strap depends on the material and frequency of use. A quality calf leather strap typically lasts 12 to 24 months with daily wear; an alligator strap with vegetable tanning can exceed 36 months, developing a distinctive patina over time. Regular exposure to water and perspiration significantly shortens the leather's life; in such cases, alternating with a rubber or NATO strap is recommended.
