Strap for Galactic Chronograph II Stainless Steel / MOP

The Breitling Galactic A1336410/A569/437X has a lug width of 20 mm. This measurement should be taken with a calliper on the inner side of the lugs, at the narrowest point between the case ears, to ensure a correct fit for any aftermarket strap.

For the Galactic A1336410/A569/437X, alligator leather is recommended for formal occasions, shell cordovan for intensive daily wear, and vegetable-tanned calf leather for a sportier register. A 20 mm steel deployant clasp is the ideal choice to maintain visual consistency with the 44 mm stainless steel case.

Strap replacement requires a fine-tipped spring bar tool. Insert the tool into the spring bar slot between the lug and the strap, compress the spring bar mechanism and slide it out. Care should be taken to avoid scratching the steel lugs; if in doubt, consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 20 mm lug width is compatible with the Breitling Galactic A1336410/A569/437X, provided the spring bars are the correct size for Breitling lugs. Milano Straps offers a selection of 20 mm straps in leather, NATO and technical materials suitable for this reference.

Longevity depends on the material and conditions of use. A high-quality shell cordovan or alligator strap, properly maintained with leather conditioner every 2–3 months and kept away from moisture, can last between 3 and 7 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
