Strap for Galactic 30 Silver / Roman / Bracelet

The lug width of the Breitling Galactic A71340L2.G670.368A is 20mm. This measurement should be taken using a digital calliper positioned between the inner walls of the lugs without applying pressure. A standard aftermarket strap at 20mm with an attachment thickness of 3.5–4.5mm fits correctly without any modification.

For the 30mm Galactic, vegetable-tanned alligator leather with Mississippiensis grain is the most coherent choice, complementing the polished case finishing. A smooth calf leather in saddlery grade offers a more understated profile, whilst vulcanised rubber is recommended for sporting use. A 20mm nylon NATO strap also echoes the brand's aviator heritage.

The strap is removed using a spring bar tool with a fine tip, inserted into the gap between the lug and the strap keeper, compressing the spring bar and sliding the strap out. It is advisable to entrust this operation to a watchmaker or the Casati Milano atelier to avoid scratching the polished steel lugs.

Yes. Any 20mm strap with standard spring bars is technically compatible with the Breitling Galactic A71340L2.G670.368A. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various materials and finishes, designed to suit the curved lugs of this model without requiring adaptation.

A quality leather strap, properly maintained, has an average lifespan of 2–4 years with daily wear. Vegetable-tanned alligator and shell cordovan, owing to their dense fibre structure, tend to outlast standard calf leather whilst developing a distinctive patina over time. Avoiding prolonged exposure to moisture and direct UV light significantly extends the strap's service life.
