Frequently asked questions

What is the lug width of the Breitling Navitimer A17327211G1A1?

The Breitling Navitimer A17327211G1A1 has a lug width of 18mm. This measurement should be taken as the internal distance between the two lugs using a digital calliper to ensure an accurate fit for any replacement strap.

What is the best strap for the Breitling Navitimer 36 A17327211G1A1?

For the steel Navitimer 36, the most fitting options are vegetable-tanned calf leather for everyday wear, a bombed alligator strap for a more formal register, and shell cordovan for a compact texture and natural lustre. A nylon NATO strap remains true to the watch's aeronautical origins.

How do you change the strap on the Breitling Navitimer A17327211G1A1?

The strap on the Navitimer A17327211G1A1 is removed using a spring bar tool. Insert the tip into the spring bar slot, compress inward and slide the strap free from the lug. Work on a soft surface to avoid scratching the stainless steel case during the operation.

Are there aftermarket straps compatible with the Breitling Navitimer A17327211G1A1?

Yes. Any strap with an 18mm attachment width is compatible with the Navitimer A17327211G1A1, provided the tail thickness suits the lug geometry. Milanostraps.it offers a curated selection of handcrafted 18mm straps made from selected leathers.

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

Longevity depends on leather type and usage. A quality vegetable-tanned calf strap typically lasts 2–4 years with daily wear. Alligator and shell cordovan tend to last longer due to their denser fibre structure. Avoiding prolonged exposure to water and perspiration significantly extends strap life.
