Navitimer A17327211G1P1— lug 18mm

The Breitling Navitimer A17327211G1P1 has a lug width of 18mm. This measurement should be taken internally between the two lugs using a calliper, and is the correct width to specify when ordering any replacement or bespoke strap.

For the 36mm steel Navitimer, a smooth alligator belly strap in burgundy or midnight blue complements the instrument dial without competing with it. Shell cordovan is an excellent choice for those seeking a tight-grained, durable surface that improves with wear. Vegetable-tanned calf leather suits a more casual-formal register, while a nylon NATO strap gives an authentic aviation aesthetic.

Use a springbar tool to release the spring bars from the lugs. With an 18mm lug width, a fine-tipped tool is recommended to avoid scratching the stainless steel case. The operation takes under two minutes and can be performed at home with the correct equipment, or entrusted to a watchmaker or specialist atelier.

Yes. Any strap with an 18mm attachment width is compatible with the Navitimer A17327211G1P1. It is worth checking the lug curvature as well: the Navitimer features slightly curved lugs, so a straight-ended strap may not sit flush against the case. Casati Milano straps for 18mm lugs are shaped to ensure a precise fit.

Longevity depends on leather quality and daily wear conditions. A vegetable-tanned calf strap typically lasts 12 to 24 months with regular use; shell cordovan or high-grade alligator can last 3 to 5 years when kept away from water and heavy perspiration. A deployant clasp reduces mechanical stress at the strap ends and significantly extends service life.
