Strap for Galactic 36 Automatic Stainless Steel / Rose Gold / Pearl Diamond / Teju

The lug width of the Breitling Galactic C3733012/A725/112Z/A16BA.1 is 18mm. This measurement should be taken with a digital calliper positioned inside the lugs, in contact with the vertical walls of the case, to ensure precise compatibility with a replacement strap.

Given the two-tone stainless steel and rose gold case of the Galactic, a Louisiana alligator strap with a gloss finish in bordeaux or cognac tones is the most aesthetically coherent choice. For daily wear in a less formal context, box calf in nude or cream tones offers durability and discretion. The 18mm lug width is also compatible with vulcanised rubber or two-tone NATO straps.

To replace the strap, you will need a quality spring bar tool, preferably with a fine 0.7mm tip to avoid scratching the rose gold lugs. Compress the spring bar by levering between the lug and the strap, remove the bar, and insert the new strap. It is advisable to work on a soft surface and, for first-time replacements, to consult a watchmaker or the Casati Milano atelier.

Yes. The 18mm format is supported by numerous quality aftermarket manufacturers. milanostraps.it offers a curated selection of 18mm straps in leather, rubber and fabric compatible with this model, available in standard and bespoke lengths. For two-tone references with rose gold components, a rose gold PVD or yellow gold buckle is recommended for visual consistency.

The longevity of a leather strap depends on the tanning method, frequency of use, and care. A vegetable-tanned alligator strap, properly conditioned with a dedicated cream and protected from direct moisture, typically lasts 3 to 5 years with regular use. Shell cordovan, owing to its dense fibre structure, tends to last longer while developing a distinctive patina. Avoiding prolonged exposure to water, perspiration and perfume significantly extends the strap's lifespan.
