Navitimer A17327361L1A1— lug 18mm

The Breitling Navitimer A17327361L1A1 has a lug width of 18 mm. This measurement refers to the internal distance between the two case lugs and determines compatibility with any replacement strap. It is advisable to verify the measurement with a calliper before purchasing an aftermarket strap.

For the 36 mm Navitimer A17327361L1A1, the most suitable straps are smooth alligator (black or brown), vegetable-tanned calf leather for those seeking a natural patina, or nylon NATO to reference the watch's aeronautical origins. An ardillon buckle in steel is preferable to a deployant clasp in order to maintain correct proportions with the 36 mm case.

The strap is removed using a spring bar tool inserted into the lug slot. By pressing the spring bar pin inward, the strap releases from the case lug. This operation should be carried out on a soft surface to avoid scratching the case. With an 18 mm lug width, the majority of standard straps are immediately compatible.
