Strap for Navitimer Rattrapante Stainless Steel / Stratos Gray / Croco / Pin / Boutique Edition

The Breitling Navitimer AB03102A1F1P2 has a lug width of 24mm. This measurement is taken directly between the case lugs using a millimetre calliper and is the essential parameter for selecting any compatible aftermarket strap.

For the 45mm Navitimer AB03102A1F1P2, an alligator leather strap with a deployant clasp is the most technically coherent choice: it visually balances the case's mass and ensures consistent fit. A vegetable-tanned calf leather strap suits everyday wear, whilst a NATO nylon strap is well suited to sporting or outdoor use.

The strap on the Navitimer AB03102A1F1P2 is secured by standard 24mm spring bars. To replace it, use a spring bar tool: insert the tip into the spring bar slot, compress and slide the strap free. No Breitling-specific tools are required; the operation can be carried out independently with care to avoid scratching the lugs.

Yes, any strap with a 24mm attachment is technically compatible with the Navitimer AB03102A1F1P2. Milano Straps offers a curated selection of handcrafted 24mm straps in various materials and finishes, available to browse online. For a fully bespoke solution, the Casati Milano atelier provides a made-to-order service by appointment.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use and exposure to perspiration and moisture. A high-quality alligator or shell cordovan strap, properly maintained (leather conditioner every 2–3 months, avoiding prolonged water exposure), will typically last 3–5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
