Strap for Navitimer 8 B01 Chronograph 43 Red Gold / Bronze / Brown Croco

The lug width of the Breitling AVI RB0117131Q1P1 is 23mm. This is a non-standard measurement compared to the more common 20mm or 22mm, and it is a defining characteristic of the entire AVI line. To verify it, use a digital calliper positioned between the lugs at the point where the strap attaches to the case.

For the Breitling AVI RB0117131Q1P1 in Red Gold, the most suitable materials are semi-gloss alligator leather in cognac or tobacco tones, shell cordovan in bordeaux or dark cherry, and vegetable-tanned calf leather with a vintage finish. These materials complement the warm reflections of red gold and develop a patina over time that is consistent with the model's aesthetic.

The strap on the Breitling AVI RB0117131Q1P1 is replaced using a springbar tool. The 23mm spring bars are removed by levering into the lug seat with the thin tip of the tool. It is recommended to work on a soft surface to avoid scratching the red gold case, and to replace the spring bars if they show signs of wear.

Yes, aftermarket straps compatible with the Breitling AVI RB0117131Q1P1 do exist, but the 23mm lug width requires bespoke production or careful selection. Milano Straps offers a range of 23mm compatible straps available online, as well as the Casati Milano bespoke service for fully personalised straps in leather, rubber, or technical materials.

The lifespan of a leather strap depends on the material, usage, and care. A quality alligator or shell cordovan strap, with regular use and periodic maintenance (conditioning cream every 3–4 months, protection from moisture), can last between 3 and 7 years. Vegetable-tanned calf leather straps generally have a shorter lifespan of 2 to 4 years, though they develop a particularly appreciated patina over time.
