Frequently asked questions

What is the lug width of the Breitling Transocean AB015212/G724/433X/A20BA.1?

The lug width of the Breitling Transocean AB015212/G724/433X/A20BA.1 is 22mm. This is the critical measurement to use when selecting any aftermarket strap, whether in leather, NATO webbing or rubber.

For the Transocean AB015212/G724/433X/A20BA.1, an alligator strap with Mississippi grain, contrast stitching and a stainless steel deployant clasp is the most coherent choice given the model's formal character.
