Strap for Navitimer Rattrapante Stainless Steel / Panamerican Bronze / Calf / Folding

The Breitling Navitimer AB031021/Q615/440X/A20D.1 features a 24 mm lug width. This is a non-standard measurement compared to the more common 20–22 mm, chosen by Breitling to visually balance the 45 mm case diameter. Always verify this measurement before purchasing any aftermarket strap.

For the Navitimer AB031021/Q615/440X/A20D.1, the most suitable options are black or navy alligator leather (for formal use), bordeaux shell cordovan (for a bespoke sartorial feel), vegetable-tanned calf leather (for daily wear with natural patina development), and nylon NATO for sporting or aviation use. A brushed steel deployant clasp is recommended for more formal pairings.

To replace the strap, a fine-tipped spring bar tool is required. Insert the tip into the lateral slot on the lug, compress the spring bar and slide the strap outwards. Proceed carefully to avoid scratching the stainless steel case. If in doubt, it is advisable to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. The Navitimer AB031021/Q615/440X/A20D.1 uses standard 24 mm spring bars, compatible with any quality aftermarket strap with a 24 mm attachment. Milano Straps offers a dedicated selection on milanostraps.it, featuring handcrafted straps in various leathers and materials, made specifically for this lug width.

The lifespan of a leather strap depends on leather quality, frequency of use, and maintenance. A high-grade alligator or shell cordovan strap, with regular care (conditioning with appropriate products, drying after moisture exposure), will retain its characteristics for 3–5 years of regular use. Vegetable-tanned leather develops a natural patina but may be more sensitive to water than treated hides.
