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

The lug width of the Breitling Navitimer AB0121211G1A1 is 22mm. This measurement should be taken between the two lugs at the inner attachment point, using a calliper or millimetre ruler. Only a 22mm strap is fully compatible with this reference.

For the Navitimer AB0121211G1A1, the most appropriate options are: alligator leather with vegetable tanning for formal wear, matte calfskin for daily use, ballistic nylon NATO for an aviatory aesthetic, and vulcanised rubber for intensive sport use. A deployante clasp extends the life of any leather strap and improves wrist comfort.

The strap on the Navitimer AB0121211G1A1 is removed using a fine-tipped spring bar tool, applying gentle pressure to lever out the spring bars housed within the lugs. It is advisable to place a soft cloth against the case to prevent scratching. To fit the new strap, insert one spring bar first, then compress the other to click it into the opposing lug.

Yes. Any aftermarket strap with a 22mm attachment width is technically compatible with the Navitimer AB0121211G1A1. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials and finishes, available either bespoke or ready to ship, including spring bars and backed by a production warranty.

The lifespan of a leather strap depends on the material, maintenance and frequency of wear. A quality vegetable-tanned alligator strap, properly cared for — avoiding prolonged moisture and applying leather conditioner periodically — can last between three and six years with daily wear. Calfskin has a shorter average lifespan but offers excellent value. Using a deployante clasp significantly reduces mechanical stress on the leather.
