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

The lug width of the Breitling Galactic A3733053/A717/236X/A16BA.1 is 18mm. This measurement refers to the internal distance between the two case lugs at the strap attachment point, and determines the correct width for any compatible aftermarket strap.

For a 36mm stainless steel case with an instrument-oriented character, the most suitable straps are vegetable-tanned calf leather, Mississippiensis alligator or shell cordovan for formal contexts, and vulcanised technical rubber for everyday or sporty use. The correct lug width is 18mm. A stainless steel keeper and buckle ensure material consistency with the case.

To replace the strap, use a fine-tipped springbar tool. Insert the tip into the lug hole to compress the spring bar, then slide the strap free. Take care not to scratch the stainless steel lugs: we recommend protecting the case with soft masking tape or entrusting the operation to a watchmaker.

Yes, any strap with an 18mm lug width is geometrically compatible with the Breitling Galactic 36. Milanostraps.it offers a curated selection of handcrafted 18mm straps in various leathers and finishes, fitted with standard spring bars compatible with the original Breitling case lugs.

The lifespan of a leather strap depends on tanning quality, grain density and frequency of wear. A quality vegetable-tanned calf strap typically lasts 2–4 years with regular use. Alligator and shell cordovan, due to their denser fibre structure, generally last longer. Prolonged exposure to water and perspiration accelerates deterioration: in humid environments, alternating with a rubber strap is advisable.
