The Aerospace E79363101B7E1, seen from the bench

The Breitling Aerospace Evo Titanium (ref. E79363101B7E1) is a professional ana-digi chronograph developed since 1985 for commercial and military pilots. The 43mm titanium case uses aerospace-grade material to reduce weight and withstand thermal and mechanical stress. It houses the Breitling 79 electronic movement, COSC-certified, with dual analog-digital display, chronograph, alarm, perpetual calendar, and 24-hour functions. The 22mm lug width is the technical standard for this family and supports a broad selection of aftermarket straps.

Frequently asked questions

What is the lug width of the Breitling Aerospace E79363101B7E1?

The lug width of the Breitling Aerospace E79363101B7E1 is 22mm. This is the standard measurement to use when selecting any aftermarket strap compatible with this reference.

What is the best strap for the Breitling Aerospace E79363101B7E1?

The choice depends on intended use. For intensive daily or sports use, vulcanised rubber or ballistic nylon NATO straps are the most practical options. For a more formal register, a belly-cut alligator strap with a deployant clasp complements the titanium case without compromising its technical character. Vegetable-tanned Tuscan calf leather offers an excellent balance between durability and refinement.

How do I change the strap on a Breitling Aerospace E79363101B7E1?

The strap is removed using a dedicated springbar tool, available at any watchmaker. The spring bars connecting the strap to the case lugs are compressed laterally to release. The procedure takes only a few minutes and carries no risk to the watch when performed with the correct tools. It is advisable to consult a watchmaker for the first intervention.

Are there aftermarket straps compatible with the Breitling Aerospace E79363101B7E1?

Yes. Any strap with a 22mm attachment width is compatible with the Breitling Aerospace E79363101B7E1. Milano Straps offers a selection of handcrafted straps in leather, rubber and nylon made specifically for this lug width, in standard lengths suitable for a variety of wrist circumferences.

How long does a leather strap last on a Breitling Aerospace?

The lifespan of a leather strap depends on the quality of the tanning, daily use and maintenance. A quality vegetable-tanned calf leather strap, kept dry and treated with appropriate products, can last between two and five years with regular wear. First-cut alligator straps, owing to the greater density of the hide, tend to offer superior longevity. Prolonged exposure to water and perspiration remains the primary factor in accelerated deterioration.
