The AVI AB0119131C1P4, seen from the bench

The Breitling AVI AB0119131C1P4 is a 43mm stainless steel chronograph faithful to 1950s RAF and US Navy aviation watches. It features the B01 in-house movement with column-wheel chronograph, COSC-certified precision, and 70-hour power reserve. The cushion-shaped case with mixed satin and polished finishing echoes vintage aircraft instruments. The 23mm lug width—non-standard by contemporary design—ensures wrist stability and visual coherence with case proportions. Functions include hours, minutes, small seconds, date, and chronograph displayed with aeronautical hierarchy for instant readability.

Frequently asked questions

What is the lug width of the Breitling AVI AB0119131C1P4?

The Breitling AVI AB0119131C1P4 features a 23mm lug width, a non-standard measurement that requires straps specifically produced or sourced for this size. Accurate measurement with a digital calliper between the inner lugs of the case is essential to ensure a precise fit.

What is the best strap for the Breitling AVI AB0119131C1P4?

For the Breitling AVI AB0119131C1P4, alligator straps with hornback grain or shell cordovan enhance the aeronautical character of the dial and age beautifully over time. A ballistic nylon NATO strap is the most historically faithful choice for a pilot watch of this pedigree, whilst vulcanised rubber is recommended for sporting or water-related use.

How do I change the strap on a Breitling AVI AB0119131C1P4?

Strap replacement on the Breitling AVI AB0119131C1P4 is carried out via standard 23mm spring bars.

How long does a leather strap last on a Breitling AVI AB0119131C1P4?

A vegetable-tanned shell cordovan or alligator strap, when regularly treated with a neutral leather conditioner and rotated with other straps, can last between three and seven years whilst developing a distinguished patina.
