Frequently asked questions

What is the lug width of the Breitling Navitimer R17395211A1R1?

The Breitling Navitimer R17395211A1R1 features an 18mm lug width. This is the internal measurement between the case lugs, consistent with the model's compact 35mm diameter. Any strap with an 18mm attachment is compatible, provided the spring bars are the correct length for the red gold case.

What is the best strap for the Breitling Navitimer R17395211A1R1?

For an 18k red gold case, the ideal strap is square-scale alligator with a polished finish, or vegetable-tanned box-calf leather in mahogany, cognac or black tones. Shell cordovan is a refined sartorial alternative. For daily wear, fine vulcanised rubber preserves the aviator character without compromising practicality.

How do you change the strap on the Breitling Navitimer R17395211A1R1?

The strap is replaced by removing the spring bars connecting it to the case. A fine-tipped spring bar tool inserted into the lug slot is sufficient. It is advisable to rest the watch on a soft cushion to protect the red gold case from scratches. A watchmaker or the Casati Milano atelier can assist with the operation.

Are there aftermarket straps compatible with the Navitimer R17395211A1R1?

Yes: any strap with an 18mm attachment is technically compatible with the Navitimer R17395211A1R1. Milanostraps.it offers a selection of handcrafted aftermarket straps in various materials. For a bespoke result, Casati Milano produces made-to-measure straps with the client choosing the leather directly at the atelier.

How long does a leather strap last on the Breitling Navitimer R17395211A1R1?

Longevity depends on the material and usage. A quality handcrafted alligator or vegetable-tanned calf strap, with proper care (leather conditioner every 2-3 months, protection from water and perspiration), typically lasts 3-5 years with gradual aesthetic wear. Shell cordovan tends to last longer due to its dense fibre structure. Casati Milano provides an 18-month warranty against manufacturing defects.
