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

The lug width of the Breitling Galactic A3733053/A717/213X/A16BA.1 is 18 mm. This is a fixed constructional specification of the model and must be matched precisely when selecting any replacement strap to ensure correct fitment and balanced proportions.

For the Galactic 36mm with its silver-toned dial, belly-cut alligator straps (in smoke grey or midnight blue) and shell cordovan (in cognac or burgundy) offer the finest balance between formal elegance and artisanal character. For sport or summer use, a quality nylon NATO strap or a vulcanised rubber strap in 18mm width are practical and aesthetically coherent choices given the model's instrumental DNA.

To replace the strap, you will need a springbar tool: insert the forked tip into the slot of the spring bar located between the case lugs, compress the bar and slide the strap free. Exercise care to avoid scratching the satin-finished steel case surfaces. For best results, we recommend entrusting the operation to a watchmaker or a specialist leather craftsman.

Yes. Any strap with an 18mm attachment width is technically compatible with the Breitling Galactic A3733053/A717/213X/A16BA.1. Milano Straps offers a curated selection of handcrafted 18mm straps — in calf leather, alligator, cordovan and NATO — made from carefully sourced materials with finishing standards comparable, and often superior in terms of personalisation, to original equipment.

The lifespan of a leather strap depends on the material, frequency of wear and level of care. A quality calf leather strap typically lasts 1–2 years with daily use. Alligator or shell cordovan straps, being denser and more resistant to perspiration, can last 3–5 years with regular maintenance — conditioning cream and rotation with other straps. Prolonged exposure to water and sweat remains the primary cause of deterioration for any natural leather.
