Strap for Navitimer B01 Chronograph 46 Stainless Steel / Blue / Bracelet

The Breitling Navitimer AB0137211C1A1 has a lug width of 24mm. This measurement is specific to the larger Navitimer references and is not interchangeable with the more common 22mm or 20mm sizes. Always verify the lug width with a digital calliper inserted between the case lugs before purchasing an aftermarket strap.

For the 46mm Navitimer AB0137211C1A1, the most suitable materials are polished belly alligator for formal occasions, vegetable-tanned calfskin in havana or cognac shades for daily wear, and ballistic nylon NATO for a pure aviation aesthetic. Given the substantial case size, a deployant clasp is recommended to distribute tension evenly across the 24mm lug.

Changing the strap on the Navitimer AB0137211C1A1 requires a fine-tip or fork-style spring bar tool, inserted into the lug hole to compress the spring bar ends. With a 24mm lug width, standard watchmaker spring bar tools are suitable. It is advisable to work on a soft surface to protect the stainless steel case from accidental scratches.

Alligator or vegetable-tanned calfskin straps, regularly treated with a leather conditioner and kept away from direct water contact, can exceed three years while retaining structural integrity and developing an attractive patina.
