Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Black / Croco / Pin

The Breitling Navitimer AB0121211B1P1 features a lug width of 22mm. This measurement is taken between the two lugs of the case using a millimetre calliper and represents the standard size required for any replacement strap compatible with this reference.

For the 43mm steel Navitimer AB0121211B1P1, a vegetable-tanned Tuscan leather strap in dark brown or tobacco is the most coherent choice with the instrument-style aesthetic of the watch. Alternatively, cross-grain alligator in midnight blue lends a more formal character. For sports or outdoor use, a ballistic nylon NATO or a technical rubber strap offers superior comfort and water resistance.

To replace the strap on the Navitimer AB0121211B1P1, you will need a spring bar tool or a fine-tipped lever to compress and remove the spring bars securing the strap to the case lugs. Remove one spring bar, release one end of the strap, then repeat on the other side. Insert the new 22mm strap in reverse order. Care should be taken to avoid scratching the case during this process.

Yes, any strap with a 22mm attachment width is compatible with the Navitimer AB0121211B1P1. Milano Straps offers handcrafted straps in leather, alligator, calf and cordovan, made to measure for this lug width. Compatibility is guaranteed by the standard lug size — no adapters or additional fittings are required.

The lifespan of a leather strap depends on the type of hide, frequency of use, and level of care. A quality vegetable-tanned calf strap, worn daily and kept away from water and excessive perspiration, typically lasts between 2 and 4 years. Cordovan and alligator, owing to their higher fibre density, can exceed 5 years while developing a distinguished patina. Using a deployant clasp reduces mechanical stress on the holes and significantly extends the strap's useful life.
