Breitling
Galactic A3733012/C824/215X/A16BA.1— lug 18mm

The lug width of the Breitling Galactic A3733012/C824/215X/A16BA.1 is 18mm. This measurement is less common than today's standard 20mm, and is characteristic of watches with a 36mm case diameter where the proportional relationship between case size and lug width is a deliberate design choice.

For a 36mm stainless steel case, a vegetable-tanned alligator strap — in black or midnight blue — best suits the dress-watch nature of the Galactic. A vegetable-tanned calf leather strap develops a distinctive patina over time, while a nylon NATO or vulcanised rubber strap provides a technically sound option for more active contexts. All are available in 18mm at milanostraps.it.

Strap replacement requires a spring bar tool with a fine tip. Insert the tip into the slot on the lug, compress the spring bar and slide the strap free. Repeat on the opposite side. Fit the new strap in reverse order. This can be done independently with the correct tools, or by any watchmaker, including the Casati Milano atelier.

Yes. Any strap with a standard 18mm attachment is compatible. Casati Milano crafts bespoke 18mm straps in alligator, calf leather, shell cordovan and rubber, with buckle or deployant clasp in stainless steel, replicating the original proportions of the Galactic without any modification to the case.

Longevity depends on the material and frequency of wear. A quality vegetable-tanned calf strap typically lasts 2–3 years with daily use. Alligator, owing to the density of its natural grain, reaches 4–5 years. Shell cordovan, given the compact fibrous structure of equine leather, is the most durable option. Casati Milano provides an 18-month warranty against manufacturing defects on all straps.
