Strap for Galactic Chronograph II

The Breitling Galactic A1336410E519131S has a lug width of 20mm. This measurement is taken with a digital calliper placed between the case lugs, parallel to the caseback. The 20mm standard ensures a wide range of compatible aftermarket straps.

For the 44mm steel Galactic, a vegetable-tanned calfskin strap offers the best balance of durability and elegance, developing a characteristic patina over time. Polished alligator is the preferred choice for formal settings, whilst NATO nylon or vulcanised rubber are better suited to intensive sport use or humid environments.

Strap replacement requires a fine-tipped spring bar tool or a dedicated screwdriver. Compress the 20mm spring bar housed in the lug, remove the original strap and fit the new one, ensuring the spring bar clicks securely into both lug holes. With the correct tools, the operation takes approximately two minutes.

Yes. Any strap with a 20mm attachment width is technically compatible with the Breitling Galactic A1336410E519131S. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, NATO and rubber made specifically for this lug width, with buckle widths available between 18 and 20mm.

Longevity depends on leather type and usage. A quality vegetable-tanned calfskin strap, with regular conditioning and rotation, will retain its structural and aesthetic integrity for 2–4 years. Alligator, being denser and more perspiration-resistant, can exceed 5 years with proper care. Prolonged water exposure significantly shortens strap life.
