At a hefty 48mm in diameter and 17.25mm thick, the new Superocean is certain to make an impression. And size isn't its only attribute; it offers everything the perfect dive watch should have, from 300-metre water-resistance to a wide, unidirectional rotating bezel in blue ceramic and excellent legibility, even at low visibility underwater, thanks to the Super-LumiNova® coating on the hands and markers. Breitling has then upped the ante with the addition of a bezel lock and a soft-iron inner case that protects the movement against magnetic fields. Not forgetting the all-important reliability of the chronometer-certified Breitling 17 calibre.
