Strap for Galactic 36 Automatic Stainless Steel / Rose Gold / Copperhead Bronze / Calf

The lug width of the Breitling Galactic 36 reference C3733012/Q584/416X/A16BA.1 is 18mm. This measurement is taken by inserting a calliper or millimetre ruler between the two parallel lugs of the case, at the point of contact with the spring bar. Respecting this measurement is essential to ensure a correct and secure fit between the case and the strap.

For the bi-colour rose gold and stainless steel case of the Galactic 36, a vegetable-tanned alligator strap in bordeaux, cognac or tobacco brown is the most coherent choice both aesthetically and technically. The regular grain of alligator leather complements the refined case finishing, whilst vegetable tanning ensures longevity and the development of a personal patina over time. Shell cordovan is a refined alternative for a smooth, compact surface. A deployant clasp in rose gold or steel is recommended to distribute pressure evenly across the lug.

The strap on the Galactic 36 is replaced using a spring bar tool (or 1.0–1.2mm pin pusher), inserting the tip into the notch of the spring bar located inside the lug. Compress the spring bar, slide out the strap, and insert the new one whilst keeping the bars aligned with the lug holes. It is advisable to work on a soft surface to avoid scratching the bi-colour case, and to ensure the spring bar is fully extended before applying any tension.

Yes. Any strap with an 18mm lug width and a straight or lightly tapered end is compatible with the Galactic 36. Milano Straps offers a selection of 18mm straps in alligator, calf leather, shell cordovan, rubber and NATO, dimensioned specifically for this model. For those seeking a bespoke strap with personal choice of materials, Casati Milano provides a made-to-measure service with a production guarantee.

Longevity depends on the type of leather, frequency of wear and maintenance. A quality artisan vegetable-tanned alligator strap, with moderate daily use, typically lasts 3–5 years. Prolonged contact with water, perspiration and perfume accelerates deterioration of the surface layer: it is recommended to apply a leather conditioning cream periodically, avoid immersion and rotate between multiple straps. Shell cordovan offers superior resistance to flexion and can last well beyond 5 years with appropriate care.
