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

The Breitling Navitimer AB031021/Q615/439X/A20BA.1 features a 24mm lug width, a specific dimension that requires bespoke artisan straps. This intermediate measurement is characteristic of the Navitimer family in this configuration and falls outside common standards (20mm, 22mm, 26mm), making compatibility verification essential before purchase.

For this reference, we recommend alligator in vegetable-tanned leather—black or brown—which amplifies the chronograph's professional identity whilst maintaining understated elegance. Alternatively, warm reddish or havana calf offers versatility, whilst navy NATO replicates authentic historical aviation aesthetics. Choice depends on use: formal luxury suggests alligator, daily versatility demands calf, functional purism favours NATO.

Strap change requires a spring bar removal tool: position it perpendicular to the lug to depress the pin inward, lift away the old strap, and repeat on the opposite lug. Reverse the procedure for new strap installation, ensuring pins seat completely. For 24mm lugs, we recommend verifying the new strap's precision measurement before executing the change.

An artisan leather strap of quality (alligator or calf with vegetable tanning) lasts 3–5 years with moderate daily wear, developing visible patina within 6–12 months. Longevity depends on sun exposure, humidity, frequency of wear, and maintenance (periodic cleaning, avoiding prolonged water contact). Milano Straps provides specific care instructions for each leather type upon delivery.
