Galactic A1336410F517379A— lug 20mm

The Breitling Galactic A1336410F517379A has a lug width of 20mm. This measurement is taken internally between the two case lugs and is the essential parameter for selecting a compatible replacement strap. Using a digital calliper ensures an accurate reading to the nearest tenth of a millimetre.

For the Galactic A1336410F517379A, an alligator strap with square scale or hornback grain provides the best balance between technical character and refinement. Alternatively, a vegetable-tanned calfskin strap developing a natural patina, or a vulcanised rubber strap, suits more active or daily use. The correct width is 20mm.

To replace the strap, use a spring bar tool with a fine tip: insert the tool into the gap between the lug and the strap keeper, compress the spring bar and slide the strap outwards. Repeat on both sides. Insert the new 20mm strap by compressing the spring bars and hooking them into the lug holes. It is advisable to work on a soft cushion to prevent scratches to the case.

Yes. The standard 20mm lug width of the Galactic A1336410F517379A ensures full compatibility with a wide range of high-quality aftermarket straps. Milanostraps.it stocks straps in alligator, calfskin, shell cordovan, NATO nylon and rubber, all sized for 20mm lugs, with standard buckle or steel deployant clasp options.

The lifespan of a leather strap depends on tanning quality, frequency of wear and maintenance. A high-grade vegetable-tanned calfskin strap, worn in rotation and kept away from excessive perspiration and direct rain, typically lasts 2–4 years before replacement is needed. A well-maintained alligator strap can exceed 5 years. Casati Milano offers an 18-month warranty against manufacturing defects.
