Strap for Galactic 36 Automatic Stainless Steel / Diamond / Volcano Black Diamond / Calf

The lug width of the Breitling Galactic A3733053/BD02/414X/A16BA.1 is 18mm. This measurement is dictated by the proportions of the 36mm case and must be observed within a tolerance of ±0.3mm to ensure proper spring bar engagement and a clean profile between the lugs.

The most coherent choices for this model are vegetable-tanned alligator leather for a formal and refined pairing, shell cordovan for those who favour a leather that develops a rich patina over time, and vulcanised rubber for more technical or sporting use. A deployant clasp in brushed steel perfectly complements the functional aesthetic characteristic of Breitling.

Strap replacement is carried out using standard 18mm spring bars. A fine-tipped spring bar tool is sufficient to compress the pins and remove the existing strap. It is advisable to work on a soft surface to avoid scratching the brushed steel case. If in doubt, we recommend consulting a watchmaker or the Casati Milano atelier.

Yes, any strap with an 18mm attachment and standard length is technically compatible. It is important to verify the end type (straight or curved) to ensure proper fit against the lugs. Milano Straps offers a curated selection of handcrafted 18mm straps suited to this case design.

The longevity of a leather strap depends on the quality of the tanning process, the thickness of the hide, and conditions of use. A high-quality artisan alligator or shell cordovan strap, worn daily with reasonable care, can last between three and five years. Prolonged exposure to perspiration and water is the primary cause of deterioration; leather straps are not recommended during intense physical activity.
