Frequently asked questions

What is the lug width of the Breitling Navitimer AB031021/Q615/754P/A20BA.1?

The lug width of the Breitling Navitimer AB031021/Q615/754P/A20BA.1 is 24mm. This measurement is specific to the 45mm model and derives from historical aerospace standards. When selecting a replacement strap, ensure it is constructed for this precise dimension.

What is the best strap for the Breitling Navitimer AB031021/Q615/754P/A20BA.1?

The ideal strap depends on intended use and personal preference. For historical authenticity, we recommend alligator in brown or black, recalling aviation's golden era. For contemporary elegance, vegetable-tanned calf leather with natural patina development. For tactical practicality, a Cordura NATO strap. Milano Straps produces artisanal straps customisable in leather, dimensions, and finishes.

How do I change the strap on the Breitling Navitimer AB031021/Q615/754P/A20BA.1?

The Navitimer uses removable lugs secured by threaded lateral spring bars. A specialised tool is required to unscrew the lugs, then insert the new strap and retighten. If uncertain, consult a professional: Milano Straps and Casati Milano provide fitting services.

Can I use an aftermarket strap on my Navitimer AB031021/Q615/754P/A20BA.1?

Yes, provided the strap is constructed for the 24mm lug width and features compatible attachments (threaded lateral spring bars). Artisanal straps from Milano Straps are engineered specifically for this dimension and offer superior quality to generic factory straps.

How long does a leather strap last on the Breitling Navitimer AB031021/Q615/754P/A20BA.1?

A vegetable-tanned leather strap typically lasts 3–5 years with daily use and regular maintenance (occasional cleaning and conditioning). Alligator and shell cordovan exhibit superior durability, lasting 7–10 years. Milano Straps warrants artisanal straps for 18 months, with restoration and replacement options available.
