Strap for Galactic Chronograph II

The lug width of the Breitling Galactic A1336410F517131S is 20mm. This measurement refers to the inner distance between the lugs at the point where the strap attaches to the case. Use a digital calliper positioned between the lugs for an accurate reading. Any 20mm strap will be compatible with this reference.

The ideal strap depends on the intended use. For formal or business settings, a 20mm alligator strap — either glazed or matte — complements the stainless steel case with refined elegance. For everyday wear, vegetable-tanned calfskin offers durability and breathability. In sporty or water-adjacent contexts, vulcanised rubber is the most practical choice. A ballistic nylon NATO strap echoes the brand's aviation heritage with understated authenticity.

To change the strap on the Breitling Galactic A1336410F517131S, you will need a spring bar tool — a dual-ended instrument used to compress the spring bars housed within the lugs. Insert the forked tip between the case and the strap end, gently push the spring bar inward until it clears the lug hole, then repeat on the opposite side. The entire operation takes approximately two minutes and poses no risk to the case when performed with the correct tool.

Yes, any aftermarket strap with a 20mm attachment width is compatible with the Breitling Galactic A1336410F517131S. It is important to ensure that the included spring bars are made from stainless steel and are the correct length for this model's lugs. Milano Straps offers a curated range of handcrafted 20mm straps in various materials and finishes, with bespoke options available through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to perspiration and moisture. A quality calfskin strap worn daily typically lasts between 12 and 24 months. A high-grade alligator strap, owing to its denser grain and superior finish, can last between 3 and 5 years with proper care. Milano Straps products are covered by an 18-month manufacturing warranty.
