Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Black / Japan Special Edition

The Breitling Navitimer AB0121211B2A1 features a lug width of 22mm. This is the standard measurement for the 43mm Navitimer case and is compatible with most aftermarket straps available in this size.

For the stainless steel Navitimer AB0121211B2A1, alligator leather or vegetable-tanned calf leather straps are the most coherent choices, given the watch's technical yet elegant character. A nylon NATO strap suits casual or active daily wear, while vulcanised rubber with a deployant clasp is recommended for sports use. Colour pairing depends on the dial: cognac works well on dark dials; navy or dark grey on lighter ones.

The strap is removed using a fine-tipped spring bar tool, applying gentle pressure to release the spring bar connecting the strap to the case lug. It is advisable to work on a soft surface to avoid scratching the case. Alternatively, a specialist atelier such as Casati Milano can perform the replacement professionally.

Yes. Any strap with a 22mm lug width is compatible with the Breitling Navitimer AB0121211B2A1. Milanostraps.it offers a range of handcrafted options in leather, rubber, and textile, all featuring standard 22mm attachments and spring bars included.

The lifespan of a leather strap depends on the quality of the hide and the conditions of use. A high-quality alligator or calf leather strap, properly maintained — dried after moisture exposure and occasionally treated with leather conditioner — can last between 2 and 5 years. Casati Milano offers an 18-month guarantee covering manufacturing defects.
