The Heritage

The Navitimer 1 35 Automatic in 18k Red Gold (ref. R17395211A1P1) features a 35mm case diameter with an 18mm lug width. The watch houses the Breitling Caliber 17 ND movement, an ETA-based caliber with in-house decoration and regulation. The iconic circular slide rule bezel, unchanged since 1952, remains a functional tool precisely engraved on the rotating bezel. The warm color temperature of the rose gold case complements the dial counters and hands. This compact 35mm Navitimer balances presence on the wrist with legibility of the information-dense dial.

FAQ

What is the lug width of the Breitling Navitimer R17395211A1P1?

The Breitling Navitimer R17395211A1P1 features 18mm lug width. This measurement is specific to the 35mm red gold variant and differs from larger Navitimer references, which can reach 22mm. Before purchasing an aftermarket strap, it is advisable to verify the lug width using a digital calliper placed between the two lugs at their narrowest point.

What is the best strap for the Breitling Navitimer R17395211A1P1?

For an 18-carat red gold case, an alligator strap with vegetable tanning is the most coherent choice both aesthetically and technically. Bordeaux, cognac or tobacco brown shades complement the warm tones of the red gold. Shell cordovan is a more compact and long-lasting alternative, developing a natural patina that improves over time. For the clasp, a red gold or PVD gold deployant buckle provides metallic symmetry with the case and enhances wearing comfort.

How do I change the strap on a Breitling Navitimer R17395211A1P1?

To replace the strap on the Navitimer R17395211A1P1, a fine-tipped or fork-style spring bar tool is required. Insert it into the lug slot to release the spring bar. The lugs on this model are curved and relatively low-profile, so a slim spring bar tool is recommended to avoid scratching the red gold case. The operation can be performed carefully at home or entrusted to a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Navitimer R17395211A1P1?

Yes, the Navitimer R17395211A1P1 accepts aftermarket straps with an 18mm attachment, provided the strap end is shaped to fit Breitling's curved lugs. Milanostraps.it offers a curated selection of handcrafted 18mm straps in alligator, calf leather and shell cordovan, all compatible with this reference. When ordering, please specify that the strap is intended for a Navitimer with curved lugs to ensure a correct fit.

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 box-calf strap worn daily typically lasts 18 to 24 months before showing significant wear. Vegetable-tanned alligator, due to its denser fibre structure, can last over 3 to 4 years with proper maintenance (conditioning cream every 2 to 3 months, drying away from heat sources). Shell cordovan is the most durable option, offering superior resistance even under moderate humidity conditions.
