Strap for Galactic 32 Two Tone MOP / DIamond / Bracelet

The Breitling Galactic B71356L2.A710.367A has a lug width of 20mm. This measurement is taken between the two lugs of the case using a millimetre calliper, at the point where the strap sits. It is the essential parameter for selecting any compatible aftermarket strap.

For the Galactic B71356L2.A710.367A, with its mother-of-pearl dial and yellow gold details, a polished alligator strap in black or midnight blue is the most refined choice. A vegetable-tanned calf leather strap in cognac or tan complements the gold accents beautifully. For more active use, vulcanised rubber provides durability and comfort without compromising aesthetics.

To replace the strap on the Galactic, you will need a spring bar tool — preferably with a forked tip to avoid scratching the yellow gold lugs. Insert the tool into the spring bar slot, compress the spring end and slide the strap free. The process takes approximately two minutes per side and can be carried out at home with the correct tool, or entrusted to a watchmaker or the Casati Milano atelier.

Yes. The standard 20mm lug width of the Galactic B71356L2.A710.367A is one of the most widely supported sizes in the aftermarket. Milanostraps.it offers a selection of handcrafted leather, rubber and NATO straps with a 20mm attachment, made from carefully sourced materials and fully compatible with the original Breitling lugs. Bespoke options are available through the Casati Milano atelier.

The lifespan of a leather strap depends on the material, maintenance and exposure to perspiration and moisture. A quality alligator strap, kept dry and treated periodically with appropriate conditioners, can last between three and five years with daily wear. Vegetable-tanned calf leather has a similar lifespan and develops a distinctive patina over time. Shell cordovan is the most durable option, as its compact fibre structure resists surface wear far more effectively.
