Strap for Navitimer 01 46 Stainless Steel / Stratos Grey / Rubber

The lug width (distance between lugs) of the Breitling Navitimer AB01271A.F570.252S is 24mm. This measurement represents the internal space between the two lugs where the strap attaches. To verify it accurately, place the watch on a flat surface and measure from inside to inside between the two lugs, avoiding margins and approximations. Even a half-millimetre error can compromise the aesthetic and functional fit of the strap.

For a chronograph of this aviator heritage, we recommend: alligator with natural grain for supreme elegance; vegetable-tanned calfskin for mature patina and predictable ageing; shell cordovan for natural brilliance and exceptional resistance to abrasion; FKM rubber or vulcanised silicone for casual-sport use; NATO or perlon for authentic military-aviator aesthetics. Choice depends on daily use and aesthetic preference. The deep navy dial pairs magnificently with cognac calfskin, black alligator, or anthracite rubber.

The Navitimer AB01271A.F570.252S is disassembled using a dedicated spring bar tool. Insert the small tip into the lateral slot of the lug, press gently to release the internal retention spring, then extract the bar. Repeat on the opposite side. Insert the new 24mm strap by aligning the spring bar holes with the lugs, and press until the snap-lock engages. We recommend working on a soft surface (carpet) to avoid damage to the case.

All straps with a 24mm lug width are compatible with the Navitimer AB01271A.F570.252S, regardless of brand. Milano Straps offers a curated selection of artisanal 24mm straps, customisable in dimensions, initials and stitching thread. The Casati Milano atelier also creates custom-made straps with personal leather selection, WhatsApp updates and 18-month warranty.

The lifespan of a leather strap depends on the tanning method and intensity of use. Vegetable-tanned calfskin resists 2–4 years with moderate daily use, thanks to natural ageing that enhances its patina. Alligator, being thicker and more compact, reaches 4–6 years. Shell cordovan, due to its density and treatment, lasts 5–7 years or more. Vulcanised rubber can reach 8–10 years. Storing the watch in dry environments, avoiding prolonged sun and humidity exposure, and occasionally applying a nourishing balm significantly extend strap lifespan.
