Strap for Galactic 36 Automatic Rose Gold / Pearl Diamond /

The Breitling Galactic H3733012.A725.120Z has a lug width of 18 mm. To verify this directly on your piece, use a digital calliper to measure the internal distance between the two lugs at the point where the strap attaches to the case: the correct reading is 18.0 mm.

For an 18kt rose gold case, the most suitable materials are hornback alligator in bordeaux or dark brown, shell cordovan in burgundy, and vegetable-tanned calfskin. These materials complement the warm tone of the precious metal and develop a patina that remains consistent with the watch's aesthetic over time.

Strap replacement requires a spring bar tool or a flat-tipped instrument. By compressing the spring bar connecting the strap to the lug, the original strap can be removed without specialist tools. It is recommended to work on a soft surface to avoid scratching the rose gold case.

Yes. Aftermarket straps with an 18 mm lug width and 1.5 mm diameter spring bars are compatible with the Breitling Galactic 36. Milano Straps offers a curated selection of handcrafted 18mm straps verified for this reference, available both online and bespoke through the Casati Milano atelier.

The lifespan of a leather strap depends on the material and frequency of wear. A quality alligator strap, with regular maintenance and protection from heavy moisture, typically lasts between 3 and 6 years. Cordovan and vegetable-tanned calfskin develop a patina that enriches their appearance over time, maintaining structural integrity for at least 2 to 4 years with daily wear.
