Strap for Galactic 32 Two Tone MOP / Diamond / Calf

The lug width of the Breitling Galactic B71356L2.A710.406X is 20mm. This measurement is taken between the two lugs at the point where the strap attaches to the case, and is the critical parameter for compatibility with any aftermarket strap.

For this model featuring a mother-of-pearl dial and a stainless steel and yellow gold case, a vegetable-tanned alligator strap — preferably in navy, burgundy or cognac — offers the finest aesthetic balance. A yellow gold butterfly deployante clasp completes the metallic harmony with the case. For a more casual register, an ivory-toned nylon NATO strap is a considered alternative.

Strap replacement requires a spring bar tool to release the spring bars from the 20mm lugs. The operation can be carried out by a watchmaker or a skilled craftsman. It is advisable to entrust this to a professional to avoid scratching the yellow gold case components or damaging the lug surfaces.

Yes, any strap with a 20mm attachment width is technically compatible with the Breitling Galactic B71356L2.A710.406X. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, NATO and rubber, all available in 20mm, with bespoke personalisation options through the Casati Milano atelier.

Longevity depends on leather quality and frequency of wear. A high-grade vegetable-tanned alligator strap, properly maintained, can last between three and five years whilst developing a distinguished patina. A standard smooth calf strap typically has a lifespan of one to two years. Prolonged exposure to water and perspiration should be avoided, as both accelerate fibre degradation.
