Strap for Galactic 36 Automatic Stainless Steel / Volcano Black / Bracelet

The lug width of the Breitling Galactic A3733012/BA33/376A is 18mm. This measurement refers to the internal distance between the two lugs at the strap attachment point and determines compatibility with any aftermarket or bespoke replacement strap.

For the Galactic 36mm in stainless steel, an alligator strap in vegetable-tanned leather or a smooth domed calf leather strap are the most coherent choices given the model's instrumental character. Vulcanised rubber is recommended for sporting use, whilst shell cordovan suits a collector-oriented personalisation. All straps must have an 18mm attachment width.

The strap on the Galactic A3733012/BA33/376A is replaced using an 18mm spring bar and a lever tool to remove the original spring bar. Care should be taken not to scratch the stainless steel lugs: a soft cloth or protective tape over the lugs is advised during the operation. A watchmaker can complete the swap in a matter of minutes.

Yes. Any strap with an 18mm attachment width is technically compatible with the Breitling Galactic A3733012/BA33/376A. MilanoStraps offers a curated selection of handcrafted straps in various materials — leather, alligator, shell cordovan, NATO and rubber — specifically in 18mm widths, both as ready-to-ship options and as bespoke commissions through Casati Milano atelier.

The longevity of a leather strap depends on the quality of the tanning, the leather's thickness and daily usage. A high-quality vegetable-tanned strap, stored away from standing water and direct heat, will maintain its structural and aesthetic integrity for 3–5 years of regular wear. Shell cordovan, owing to the density of its fibres, tends to last longer and develops a distinctive patina over time. Casati Milano straps carry an 18-month warranty against manufacturing defects.
