Strap for Navitimer 8 B01 Chronograph 43 Stainless Steel / Silver / Calf

The lug width of the Breitling AVI AB01171A1G1X1 is 23mm. This is a non-standard size compared to the more common 22mm. It is essential to purchase straps specifically made for this dimension, as a 22mm strap would sit visibly narrower within the lugs and would lack the mechanical stability required for secure attachment.

For the Breitling AVI AB01171A1G1X1, the most suitable materials are large-grain alligator leather for a formal aesthetic, vegetable-tanned calfskin with a military finish for an authentic pilot look, and shell cordovan for those who appreciate a leather that develops a rich patina over time. For sport or water-adjacent use, a moulded rubber strap or ballistic nylon NATO are functional choices that complement the tool watch spirit of the reference.

Replacing the strap on the Breitling AVI AB01171A1G1X1 requires a springbar tool. Insert the forked tip into the lug slot to compress the spring bar and release the strap. Care should be taken to avoid scratching the stainless steel case — protecting the surfaces with low-tack adhesive tape is recommended. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Yes, high-quality aftermarket straps are available for the Breitling AVI AB01171A1G1X1, provided they are produced in the exact 23mm lug width. Milanostraps.it offers a dedicated selection of 23mm straps in various materials — leather, rubber, and textile — crafted to artisanal standards appropriate for a timepiece of this calibre.

The lifespan of a leather strap depends on material quality, care, and daily use. A handcrafted alligator or shell cordovan strap, properly maintained — wiped dry after wear, conditioned periodically with a neutral leather conditioner, and rotated with other straps — can last between 3 and 7 years while retaining its structural integrity. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
