The Navitimer A2432212/G571/443A, seen from the bench

The Navitimer World is a professional aviation chronograph born in 1952 for aircraft pilots. The reference A2432212/G571/443A features a 46mm stainless steel case with a circular slide rule bezel for speed, fuel consumption and flight range calculations. It houses the Breitling Caliber 24 movement with a tricompax layout, independent 24-hour hand, date window and complete chronograph function. The 24mm lug width reflects the Navitimer's design philosophy of proportion and readability. Stainless steel construction provides structural durability and sport-professional finishing with alternating satin and polished surfaces.

Frequently asked questions

What is the lug width of the Breitling Navitimer A2432212/G571/443A?

The Breitling Navitimer A2432212/G571/443A features 24mm lugs — one of the widest lug widths found in civilian sport watchmaking. It is essential to use straps with a precise 24mm attachment to ensure a secure and gap-free fit between the case lugs.

What is the best strap for the 46mm Breitling Navitimer?

For the 46mm Navitimer, alligator straps in Belly or Hornback grain offer the best balance between elegance and visual weight. Alternatively, vegetable-tanned calfskin develops an authentic patina over time. For sports use or water exposure, vulcanised rubber with a grip texture is the most technically coherent choice given the instrument-oriented nature of the watch.

How do you change the strap on a Breitling Navitimer?

The Navitimer strap is secured by standard 24mm spring bars. A spring bar tool or a thin flat-head screwdriver inserted into the lug slot is sufficient to compress the bar and release the strap. It is advisable to work on a soft surface to avoid scratching the case. If in doubt, any qualified watchmaker can carry out the replacement in a matter of minutes.

Are there aftermarket straps compatible with the Navitimer A2432212/G571/443A?

Yes. Any strap with a 24mm attachment and standard taper (typically 24/22mm) is compatible with the Navitimer A2432212/G571/443A. Milano Straps offers a selection of handcrafted straps in various leathers and rubber, supplied with spring bars and available with a traditional buckle or a steel deployant clasp.

How long does a leather strap last on a Breitling Navitimer?

Longevity depends on leather quality, frequency of wear, and exposure to perspiration and moisture. A quality leather strap — alligator, cordovan, or vegetable-tanned calfskin — worn daily typically lasts between 18 and 36 months. Using a deployant clasp reduces mechanical stress on the strap and can significantly extend its service life. Casati Milano straps carry an 18-month warranty against manufacturing defects.
