Strap for Galactic Chronograph II Stainless Steel / Black

The lug width of the Breitling Galactic A1336410/B719/743P is 20mm, measured internally between the two lugs at the base of the case. This is a standard size that ensures broad compatibility with quality aftermarket straps.

For the 44mm steel Galactic, the most suitable straps are alligator leather for formal occasions, vegetable-tanned calf leather for versatile daily wear, shell cordovan for those seeking a developing patina, and technical rubber for sporting use. The lug width is 20mm.

The strap is replaced using a spring bar tool to release the spring bars from the lugs. It is advisable to rest the watch on a soft surface and work carefully to avoid scratching the case. Alternatively, Casati Milano offers a professional strap-change service by appointment.

Yes, any strap with a 20mm lug width is compatible with the Breitling Galactic A1336410/B719/743P. Milano Straps offers a curated range of handcrafted straps in various materials, fitted with standard 20mm spring bars, compatible with the original case without any modification.

A quality leather strap — alligator, calf, or shell cordovan — on a 44mm watch in daily use typically lasts between 18 and 36 months, depending on exposure to perspiration, water, and heat. Vegetable-tanned straps develop a patina over time and, with proper maintenance (conditioning cream every 2–3 months), retain structural integrity and aesthetic quality for longer.
