Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Blue / Bracelet

The lug width of the Breitling Navitimer AB0121211C1A1 is 22mm. This measurement refers to the internal gap between the two lower lugs of the case, where the strap is fitted. Matching this measurement precisely is essential to ensure a secure fit without lateral play.

For the Navitimer AB0121211C1A1 in 43mm stainless steel, the most coherent options are vegetable-tanned Italian calfskin — ideal for those who appreciate natural patina development — and alligator leather for a more formal register. NATO nylon or technical rubber straps suit those wishing to emphasise the model's aeronautical heritage while maximising moisture resistance.

The Navitimer AB0121211C1A1 uses standard 22mm springbars. To replace the strap, a springbar tool is required: insert the tip into the springbar slot, compress the bar and slide the strap free. The operation is fully reversible and does not require any work on the case or caseback. If in doubt, consult a watchmaker.

Yes. The Navitimer AB0121211C1A1 uses standard 22mm springbars, making it compatible with any aftermarket strap in that width. On milanostraps.it you will find a curated selection of handcrafted 22mm straps in Italian calfskin, alligator, NATO and rubber, all compatible with the original lugs of this reference.

The lifespan of a leather strap depends on hide quality, tanning method and daily use. A high-quality vegetable-tanned calfskin strap, maintained with regular conditioning and kept away from direct heat, can last between two and five years with daily wear. Well-tanned alligator straps tend to last longer due to the higher fibre density. Casati Milano straps carry an 18-month manufacturing defect guarantee.
