Navitimer AB0121C4/Q605/447A— lug 22mm

The lug width of the Breitling Navitimer AB0121C4/Q605/447A is 22 mm. This measurement corresponds to the internal distance between the two lugs of the case and determines the compatible strap width. For an accurate measurement, the use of a digital calliper is recommended.

For the Navitimer AB0121C4/Q605/447A with a black dial, the most suitable straps are in glossy alligator — black or tobacco brown for formal use — vegetable-tanned calf leather for everyday wear, or a nylon NATO strap for a sporting look that honours the watch's aeronautical origins. A deployant clasp in stainless steel is the preferred closure for leather straps on this model.

To replace the strap on the Navitimer AB0121C4/Q605/447A, a spring bar tool is required to remove the spring bars from the 22 mm lugs. The watch should be rested on a soft surface to avoid scratching the bezel or caseback. Care must be taken not to damage the steel lugs. If in doubt, it is advisable to consult a watchmaker.

Yes, the Breitling Navitimer AB0121C4/Q605/447A features standard 22 mm lugs that accept any aftermarket strap of that width. On milanostraps.it, a selection of handcrafted straps in leather, alligator, calf, NATO and rubber are available, all compatible with this lug size.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use and maintenance. A high-quality alligator or vegetable-tanned calf leather strap, worn in rotation with other watches and kept away from excess water and perspiration, can last between 2 and 5 years whilst retaining a well-kept appearance. The 18-month manufacturing defect guarantee offered by Casati Milano provides additional peace of mind.
