The Breitling Galactic B71340L2.L517.166Z is a 30mm two-tone yellow gold and stainless steel watch from the Galactic family, featuring a COSC-certified quartz Breitling B71 movement with ±0.07 seconds per day precision. The integrated mesh bracelet is architecturally integral to the design. The strap size is 20mm, requiring careful proportional attention when replacing with an aftermarket strap, with Short or Regular sizes recommended for wrists up to 16.5cm.

Frequently asked questions

What is the lug width of the Breitling Galactic B71340L2.L517.166Z?

The lug width of the Breitling Galactic B71340L2.L517.166Z is 20 mm. This measurement is taken with a digital calliper positioned between the two lugs of the case, at the point of contact with the spring bar. Any standard 20 mm strap is technically compatible with this reference.

What is the best strap for the Breitling Galactic B71340L2.L517.166Z?

For the yellow gold and steel Galactic, a glossy Porosus alligator strap is the most coherent choice: the regular scale texture echoes the woven surface of the original bracelet. A vegetable-tanned calf leather strap develops a noble patina ideal for formal daily wear, while shell cordovan offers a dense, compact grain suited to intensive use.

How do I change the strap on a Breitling Galactic B71340L2.L517.166Z?

To replace the original bracelet with a leather or rubber strap, a fine-tipped spring bar tool or dedicated lug opener is required to release the spring bars from the case lugs. As the Galactic's lugs are short and closely spaced, it is advisable to entrust this operation to a watchmaker or to the Casati Milano atelier to avoid scratching the bimetallic case.

Are there aftermarket straps compatible with the Breitling Galactic B71340L2.L517.166Z?

Yes, any standard 20 mm strap is compatible with the Breitling Galactic B71340L2.L517.166Z. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan, NATO fabric and rubber specifically suited to this format. Short or Regular lengths are recommended for wrists up to 16.5 cm, given the original bracelet's short lug extension.

How long does a leather strap last on a Breitling Galactic?

The lifespan of a leather strap depends on the material and frequency of wear. A quality alligator strap with saddle stitching and water-resistant treatment typically lasts 3 to 5 years with regular use. Vegetable-tanned calf leather develops a patina and can last over 4 years if kept away from frequent moisture. Shell cordovan, owing to its dense fibrous structure, is the most durable and can exceed 5 years. Casati Milano backs every strap with an 18-month manufacturing guarantee.
