Galactic C3733012/C831/236X/A16BA.1— lug 18mm

The lug width of the Breitling Galactic C3733012/C831/236X/A16BA.1 is 18 mm. This measurement is taken between the lugs at the point where the strap attaches to the case and is the correct specification for selecting any compatible aftermarket strap.

For the two-tone rose gold and steel case of the Galactic 36, a crocodile alligator strap with traversé grain in vegetable-tanned leather is the most coherent choice given the watch's construction quality. Alternatively, box-calf develops a distinguished patina over time. For more casual settings, a tan NATO nylon or a shell cordovan in brown offer personality without conflicting with the 36 mm proportions.

The strap on the Galactic 36 is removed using a fine-tipped spring bar tool or a small flat-head screwdriver. The standard 18 mm spring bars are compressed laterally to disengage from the lugs. Care must be taken to avoid scratching the two-tone case: it is advisable to protect the surfaces with PTFE tape, or to entrust the operation to a watchmaker or a specialist atelier such as Casati Milano.

Yes, all straps with an 18 mm lug width and standard spring bars are compatible with the Breitling Galactic C3733012/C831/236X/A16BA.1. Milanostraps.it offers a dedicated selection of 18 mm straps in various materials—alligator, calf, NATO, rubber—handcrafted and compatible with the original lugs without any case modification.

The lifespan of a leather strap depends on the material, daily wear and care. A high-quality vegetable-tanned alligator strap, when rotated with other straps and protected from excessive moisture, can last between 3 and 5 years whilst maintaining good structural integrity. Calf leather typically lasts shorter (2–3 years), whilst shell cordovan is the most wear-resistant material and can exceed 5 years with proper maintenance. Casati Milano's warranty covers manufacturing defects for 18 months.
