Strap for Galactic 36 Automatic Stainless Steel / Diamond / Pearl Diamond / Bracelet

The Breitling Galactic A37330531A1A1 features 18mm lugs. This measurement refers to the internal distance between the two case lugs, where the strap attaches. It is essential to use only straps with a declared width of 18mm to ensure a correct fit and a visually balanced result on the wrist.

For a 36mm stainless steel case such as the Galactic A37330531A1A1, the most suitable straps are fine-grain Louisiana alligator for a formal setting, or shell cordovan for those seeking a living patina over time. Vegetable-tanned calf leather offers immediate suppleness. For a sportier register, a woven nylon NATO or a vulcanised rubber strap maintains the technical Breitling character.

To replace the strap on the Galactic A37330531A1A1, you will need a spring bar tool — a small forked-tip instrument available for a modest cost. Insert the tool into the gap between the lug and the strap, compress the spring bar and slide the strap free. Care must be taken not to scratch the polished steel lugs. If unfamiliar with the process, any watchmaker or the Casati Milano atelier can perform the swap in minutes.

Yes. The Breitling Galactic A37330531A1A1 uses standard 18mm lugs, a size compatible with a wide range of artisan aftermarket straps. Milano Straps offers a full selection of handcrafted 18mm straps in alligator, shell cordovan, calf leather, NATO and rubber — all fully compatible with this reference without any adapters or modifications.

The lifespan of a leather strap depends on material quality, frequency of use and maintenance. A quality alligator strap, rotated with other straps and kept away from prolonged exposure to water and perspiration, can last between three and seven years whilst retaining its structural integrity. Shell cordovan tends to improve with wear, developing a distinctive patina. Casati Milano straps carry an 18-month warranty against manufacturing defects.
