Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Blue / Croco / Folding

The Breitling Navitimer AB0121211C1P4 has a lug width of 22mm. This measurement refers to the internal distance between the two lugs of the case, measured with a digital calliper as close to the case as possible. Verifying this dimension before purchasing an aftermarket strap is essential to ensure a precise, rattle-free fit.

For the Navitimer AB0121211C1P4 with its 43mm stainless steel case, the most suitable materials are vegetable-tanned calf leather for everyday wear, matte alligator for formal occasions, and ballistic nylon NATO for a sporting look true to the watch's aeronautical heritage. The correct width is 22mm, with curved or straight ends depending on the lug configuration.

To replace the strap on the Navitimer AB0121211C1P4, a dedicated spring bar tool is required. Compress the spring bar on one side of the lug, slide the strap out laterally and remove it. Care should be taken to avoid scratching the stainless steel case: it is advisable to protect the lugs with PTFE tape or to entrust the operation to a watchmaker for the first few changes.

Yes, there is a wide range of aftermarket straps compatible with the Navitimer AB0121211C1P4.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and the care it receives. A quality vegetable-tanned calf leather strap, kept away from excessive water and perspiration and treated regularly with a nourishing cream, can last between 2 and 5 years. Alligator straps of superior quality tend to last longer due to the greater fibre density of the hide.
