Breitling Watch Superocean Heritage II Chronograph 44. A13313121B1S1. Designed with all modern-day explorers in mind, this stunning Breitling Superocean Heritage II watch combines cutting-edge technology and legendary design to bring us the ultimate Breitling chronograph for timing our diving adventures. Its 44mm stainless steel case is water resistance to 200 metres thanks to its screw locked crown and screw in case back while its high-tech black ceramic bezel is fitted with unidirectional functionality so you can safely measure oxygen levels while underwater. While the design of this Breitling Superocean Heritage II Chronograph tributes an iconic 1957 Breitling model, the impressive Breitling 13 self-winding calibre is anything but historic. This contemporary and powerful automatic movement equips the timepiece with hour, minute and subsidiary seconds, a day and date window at 3 o clock, a central chronograph seconds hand and two chronograph dials for 30 minutes and 12 hours. As well as boasting a power reserve of 48 hours, this Breitling diving chronograph watch displays each function on a smooth Volcano black dial detailed with matching black chronograph counters and an elegant steel toned Breitling logo. To complete the look of this Breitling Superocean watch, a sophisticated mesh style black rubber strap is added alongside a classic folding buckle.
