Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Airline Editions SwissAir / Calf / Folding

The Breitling Navitimer AB01211B1B1X2 features a 43 mm case with a nominal lug width of 22 mm. The opposite end typically tapers to 20 mm to accommodate standard buckles. Before purchasing an aftermarket strap, it is advisable to confirm the measurement with a calliper to rule out any production variance.

For the Navitimer AB01211B1B1X2 with a black dial and gilt indices, the most suitable options are vegetable-tanned calfskin in tobacco brown or alligator in cognac, both of which complement the warm tones of the hour markers. A nylon NATO strap references the original 1950s aeronautical aesthetic, while vulcanised rubber with a raised texture is preferable for active daily wear. A brushed steel deployant clasp completes the case finishing cohesively.

To replace the strap on the Navitimer AB01211B1B1X2, you will need a 22 mm springbar (1.8 mm diameter) and a fork-tip springbar tool. Insert the fork tip into the lateral lug slot to compress the telescopic pin securing the bar, then slide the strap free. The procedure takes approximately two minutes per side and does not require a watchmaker, provided you work on a soft surface to avoid scratching the case.

Yes. Any strap with a 22 mm lug width and standard length (long side 120 mm, short side 75 mm) is compatible with the Navitimer AB01211B1B1X2. The Navitimer's lug profile curves downward, but flat-ended straps adapt correctly due to the natural flexibility of the leather. milanostraps.it offers a curated selection of handcrafted 22 mm straps verified for compatibility with this reference.

The lifespan of a leather strap depends on leather quality, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned calfskin strap worn daily will typically last 18 to 36 months before structural wear becomes apparent. High-cut alligator straps tend to last 3 to 5 years due to the density of the grain. To extend strap life, it is advisable to rotate between two or more straps and apply a neutral leather conditioner periodically.
