Strap for Navitimer 1 38 Automatic Stainless Steel / Blue / Croco / Pin

The Breitling Navitimer A17325211C1P1 has a lug width of 20mm. This measurement is taken with a millimetre calliper positioned between the inner edges of the lugs, at the point where they meet the case. Any replacement strap must match this width to ensure correct alignment and secure spring bar retention.

For the 38mm steel Navitimer A17325211C1P1, the most suitable options are vegetable-tanned calfskin with a smooth grain — ideal for everyday wear and natural patina development — or Mississippiensis alligator with a square scale pattern for more formal settings. For sport use or humid environments, a vulcanised rubber strap is the most technically appropriate choice. A NATO strap remains a versatile and tool-watch-appropriate option.

To replace the strap on the Navitimer A17325211C1P1, remove the spring bars from the 20mm lugs using a dedicated spring bar tool or a fine-tipped lever. Rest the watch on a soft cloth to prevent scratching the case. The replacement strap must be 20mm at the lugs and may taper to 18mm at the buckle end. For NATO straps, spring bar removal is not required.

Yes, the aftermarket offers an extensive range of straps compatible with the Navitimer A17325211C1P1, owing to its standard 20mm lug width. Milanostraps.it offers handcrafted straps in leather, alligator, shell cordovan and rubber, with customisable finishes. It is important to verify that the chosen strap has a tang thickness compatible with the lug clearance of this specific model.

The lifespan of a leather strap depends on the material, craftsmanship and frequency of use. A quality vegetable-tanned calfskin strap, properly maintained with periodic conditioning cream and kept away from direct heat, can last between 2 and 4 years with daily wear. A high-grade alligator strap, with less intensive use, can exceed 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
