Strap for Galactic 36 Automatic Stainless Steel / Gun Blue / Calf

The lug width of the Breitling Galactic A3733012/C824/194X/A16BA.1 is 18 mm. This measurement should be taken with a vernier calliper at the inner face of the lugs, as close to the case as possible, to ensure a precise fit without lateral play.

For the 36 mm Galactic, a vegetable-tanned calf leather strap or a flat-scale alligator strap is the most coherent choice given the dress-sport character of the reference. A steel deployant clasp is recommended to protect the strap from repeated folding and to improve wrist stability. For casual wear, a heritage-coloured nylon NATO strap is a solid alternative.

Strap replacement requires a spring bar tool — either a lever-tip or pin-tip — to compress and remove the 18 mm spring bars seated in the lug holes. It is advisable to work on a soft surface to avoid scratching the case. The operation can also be carried out by a watchmaker or at the Casati Milano atelier.

Yes. Any strap with an 18 mm lug width is dimensionally compatible. Milanostraps.it offers a curated selection of handcrafted leather, rubber and nylon straps in 18 mm, with various closure options including pin buckle and deployant clasp.

The lifespan of a leather strap depends on hide quality, tanning method and daily usage. A quality vegetable-tanned calf strap, with regular care, typically lasts between three and five years. Shell cordovan, owing to the dense fibrous structure of the hide, often exceeds five years while developing a fine patina. Prolonged exposure to perspiration, water and direct sunlight will noticeably shorten the strap's service life.
