Strap for Galactic Chronograph II Stainless Steel / Black

The Breitling Galactic A1336410/B719/435X features a lug width of 20 mm. This measurement is taken with a digital calliper positioned between the two lugs at the base of the case, at the spring bar seating point. It is the most common standard lug width in high-end Swiss watchmaking.

The choice depends on the context: for formal wear, a mississippiensis alligator strap with contrast stitching enhances the Galactic's build quality. For daily or sporting use, a vegetable-tanned calf leather or vulcanised rubber strap offers durability and comfort. A nylon NATO strap is the lightest option and consistent with Breitling's aeronautical heritage.

Strap replacement requires a double-ended spring bar tool inserted into the gap between the lug and the strap end to compress the spring bar. This can be done independently with care, or entrusted to a watchmaker or the Casati Milano atelier during a scheduled consultation.

Yes. Any strap with a 20 mm attachment and a heel thickness suited to the Galactic's lug profile is compatible. Milano Straps offers a curated selection of 20 mm straps in various materials — leather, rubber, NATO — produced with geometries tested to ensure a precise fit without lateral play or stress on the lugs.

Longevity depends on the material and conditions of use. A vegetable-tanned calf leather strap, with routine care (avoiding prolonged contact with water and perspiration, applying leather conditioner periodically), typically lasts 2–4 years. A quality alligator strap, properly maintained, can exceed 5 years. The Milano Straps guarantee covers manufacturing defects for 18 months.
