Strap for Navitimer 01 46 Stainless Steel / Aurora Blue / Croco / Pn

The lug width (ansa width) of the Breitling Navitimer AB012721/C889/746P/A20BA.1 is 24mm. This measurement is specific to the 46mm model and determined by the case geometry and internal lug spacing. To verify, measure from the inner shoulder of one lug to the other using a ruler, ensuring the strap is completely removed. No strap of different width (20mm, 22mm, etc.) will fit correctly.

For the Navitimer 46mm with black dial, we recommend a dark alligator (black or deep brown) for elegant contrast with stainless steel, or black Taurillon calf for aesthetic cohesion. If you prefer a tactile, aging solution, shell cordovan with vegetable tanning develops deep patina within 6-8 months. For professional environments with variable humidity, microperforated FKM or natural caoutchouc ensures stability and resistance. All straps must feature 24mm lug width.

Position the watch with dial facing downward on a soft surface to prevent scratches. Identify the spring bars connecting the strap to the lugs: these are small tension-held metal cylinders. Using a dedicated tool (spring bar remover) or blunt instrument, gently press the spring bar toward the centre from the outside, freeing the strap. Repeat on both sides. To fit the new 24mm strap, align the spring bars with the lug holes, press until you hear a click. Verify the strap is secure before wearing the watch.

Yes, you can use high-quality aftermarket straps provided they meet the 24mm lug width requirement. Artisanal straps in alligator, calf, or vegetable-tanned shell cordovan are fully compatible with the 46mm Navitimer and often offer superior finishes and customisation compared to originals. Ensure the strap features appropriate spring bars (universal standard) and that edges are finished correctly to prevent scratching the stainless steel lugs. Casati Milano crafts custom 24mm straps with an 18-month warranty.

Lifespan depends on material and usage. A quality artisanal alligator or calf strap lasts 3-5 years with moderate daily wear, with patina improving over time. Vegetable-tanned shell cordovan, if cared for properly (periodic application of natural balm), can exceed 7-10 years. FKM rubber lasts 2-3 years under intense sun exposure but remains functional to 4-5 years if stored away from direct light. Longevity is determined by ambient humidity, frequency of wear, and body perspiration. Artisanal leather straps are generally more durable than standard industrial straps because they are constructed with premium hides and reinforced double-stitched seams.
