Navitimer U17395211A1P4— lug 18mm

The Breitling Navitimer U17395211A1P4, in its 35mm case size, features a lug width of 18mm. This measurement is native to the 35mm format and ensures correct visual proportion between the case and the strap. To verify it independently, measure the internal distance between the two lugs with a calliper after removing the strap.

For the Navitimer U17395211A1P4, the most suitable options are: polished alligator for formal wear, shell cordovan for those seeking character and patina over time, and vegetable-tanned calfskin for maximum everyday versatility. Vulcanised rubber is recommended for sport use or humid environments. All straps must have an 18mm attachment width.

The strap on the Navitimer U17395211A1P4 is replaced using a springbar tool, widely available at low cost. Insert the tool tip into the lug slot, compress the spring bar and slide the strap outward. Repeat on the other side. The operation requires no specific watchmaking skills but should be performed carefully to avoid scratching the case.

Yes, any strap with an 18mm attachment is technically compatible with the Navitimer U17395211A1P4. Milanostraps.it offers a curated selection of handcrafted 18mm straps in various materials and finishes, manufactured to the same quality standards as original equipment straps. Compatibility is determined solely by lug width, regardless of strap brand.

Longevity depends on the material and conditions of use. A vegetable-tanned calfskin strap, with daily use and proper care, typically lasts 2–3 years before showing significant wear. Shell cordovan, owing to its dense fibrous structure, can last 4–5 years while retaining form and appearance. Alligator leather, if kept away from water and excessive perspiration, offers comparable durability to cordovan. Apply a quality leather conditioner periodically and avoid prolonged contact with moisture.
