Strap for Navitimer Automatic 36 Stainless Steel / Mint Green / Alligator

The lug width of the Breitling Navitimer A17327361L1P1 is 18mm. This measurement must be taken between the two lugs at the point where the strap attaches to the case, using a precision calliper. It is the essential parameter for selecting a compatible aftermarket strap.

For the Navitimer 36mm, the most suitable straps are vegetable-tanned calf leather — which develops an authentic patina over time — or Mississippiensis alligator with a regular grain for more formal wear. A nylon NATO strap is the functional choice for casual contexts, consistent with the watch's aeronautical DNA. The correct width is 18mm.

To replace the strap on the Navitimer A17327361L1P1, you will need a spring bar tool to remove the spring bars connecting the strap to the 18mm lugs. It is advisable to work on a soft surface to avoid scratching the stainless steel case. Alternatively, any watchmaker or specialist retailer can perform the operation in a matter of minutes.

Yes, the aftermarket offers a wide range of straps compatible with the 18mm lug width of the Navitimer 36. Milano Straps offers options in alligator, calf leather, shell cordovan and NATO, all crafted to the thickness and profile tolerances required for a correct fit on the Navitimer's lugs.

The lifespan of a leather strap depends on the quality of the hide, maintenance and daily use. A high-quality vegetable-tanned calf strap, kept away from water and excessive perspiration, can last between 2 and 5 years. Shell cordovan, being denser and more compact, tends to last longer. The Casati Milano guarantee covers manufacturing defects for 18 months.
