Strap for Galactic 36 Stainless Steel / Diamond / Pearl / Rubber

The Breitling Galactic A7433053.A779.238S has a lug width of 18mm. This is the measurement to use when selecting any aftermarket strap, whether in leather, rubber, or NATO nylon.

For the 36mm steel Galactic, lacquered alligator or shell cordovan straps are the most refined choice, as their natural grain texture complements the understated case design. For daily wear, vegetable-tanned calfskin offers the best balance of durability and aesthetics. A polished steel deployant clasp elevates the overall formal register of the watch.

Strap replacement requires a spring bar tool or a small flat-head screwdriver to release the spring bars from the lugs. It is advisable to work on a soft surface to avoid scratching the case. The 18mm lug accepts standard 1.5mm-diameter spring bars. If in doubt, a watchmaker or the Casati Milano atelier can carry out the replacement safely.

Yes. Any strap with an 18mm attachment width is compatible with this reference. The milanostraps.it collection includes alligator, calfskin, shell cordovan, NATO, and rubber options, all handcrafted and sized for an 18mm lug width. An original Breitling strap is not required to maintain the aesthetic and functional quality of the watch.

Longevity depends on the material and frequency of use. A well-maintained vegetable-tanned calfskin strap typically lasts 2–3 years with regular wear. Shell cordovan, owing to its dense fibre structure, can exceed 4–5 years. Quality alligator leather, kept away from excessive moisture, offers comparable longevity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
