Strap for Galactic Chronograph II Stainless Steel / Blue

The lug width of the Breitling Galactic A1336410/C645/379A is 20mm, measured internally between the two lugs at their narrowest point. For a correct fit, straps with 20mm nominal spring bars are recommended, with a tolerance between 19.8mm and 20.2mm.

For the Breitling Galactic A1336410/C645/379A, the most suitable materials are vegetable-tanned alligator for its dress-sport character, box-calf leather for intensive daily use, and shell cordovan for those seeking a noble patina over time. A polished steel deployant clasp is the most aesthetically coherent closure for the 44mm case.

Strap replacement on the Galactic is performed by removing the spring bars using a dedicated double-ended spring bar tool. The bars measure 20mm in width. It is advisable to work on a soft surface to protect the polished case and lug surfaces from accidental scratching.

Yes. Any strap with a standard 20mm attachment is compatible with the Breitling Galactic A1336410/C645/379A. Milano Straps offers a selection of handcrafted 20mm straps available bespoke or online, in materials including alligator, box-calf, shell cordovan, and vulcanised rubber.

The lifespan of a leather strap depends on the material and care. A quality handcrafted box-calf strap typically lasts 2–4 years with daily wear. Vegetable-tanned alligator can exceed 5 years if kept away from prolonged moisture. Casati Milano offers an 18-month guarantee against manufacturing defects on all its straps.
