The Heritage

The Breitling Navitimer 1 35 Automatic is a stainless steel chronograph with a 35mm case and 18mm lug width, powered by the Breitling Caliber 17 ND automatic movement. Originally developed in 1952 as a certified pilot's instrument, this reference A17395F41G1P4 restores the model to its historically coherent proportions with a traditional tri-register dial and peripheral tachymeter scale. The case features alternating satin and polished surfaces that enhance the geometry and construction details of the watch.

FAQ

What is the lug width of the Breitling Navitimer A17395F41G1P4?

The Breitling Navitimer A17395F41G1P4 features an 18mm lug width. This measurement is specific to the 35mm case and determines compatibility with any aftermarket strap. Before purchasing a replacement strap, it is advisable to confirm the lug width using a digital calliper, measuring the internal distance between the lugs.

What is the best strap for the Breitling Navitimer A17395F41G1P4?

For the 35mm Navitimer A17395F41G1P4, flat-belly alligator straps with vegetable tanning or shell cordovan leather are the most coherent choices given the watch's identity. A technical nylon NATO strap suits sporting use, whilst vulcanised rubber with a grip texture is appropriate for active environments. A deployant clasp in steel completes any pairing with formal rigour.

How do you change the strap on a Breitling Navitimer A17395F41G1P4?

To replace the strap on the Navitimer A17395F41G1P4, a double-tip springbar tool is required. Insert the tool into the lug groove to compress the spring bars and release the strap. Care must be taken to avoid scratching the stainless steel case; if in doubt, it is preferable to consult a watchmaker or visit the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Navitimer A17395F41G1P4?

How long does a leather strap last on the Breitling Navitimer A17395F41G1P4?

The longevity of a leather strap depends on the quality of the hide, the tanning process and daily use.
