Strap for Navitimer 8 Chronograph 43 Blacksteel / Black / Black Calf

The lug width of the Breitling AVI M13314101B1X1 is 23mm. This is a non-standard measurement inherited from the original Ref. 765 of 1953, requiring straps made specifically for this dimension. It is advisable to verify the measurement with a digital calliper before purchasing.

For the Breitling AVI M13314101B1X1, the most suitable straps are vegetable-tanned alligator (Hornback or Mississippi grain) for formal wear, hand-stitched calf leather for everyday use, shell cordovan for those seeking longevity and natural patina, or olive green NATO nylon to honour the watch's aeronautical heritage.

The strap on the Breitling AVI M13314101B1X1 is replaced using a spring bar tool. Insert the tip of the tool into the lateral hole of the lug to compress the spring bars and slide the strap out. No specialist technical skills are required, though it is advisable to work on a soft surface to avoid scratching the case.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned alligator strap, kept away from water and excessive perspiration and treated periodically with leather conditioner, can last between 3 and 7 years. Shell cordovan is generally more resistant to wear and tends to last longer, developing a distinctive patina over time.
