Since its launch in 2009, the Supermarine collection has gone from strength to strength. Its unique design and capabilities to withstand extreme conditions have not only been extensively tested out in the field by Bremont's ambassadors but also numerous elite military squadrons and top dive units around the world. In line with Bremont’s more technical Supermarine models, this new timepiece incorporates certain vital functions required for extreme diving, in particular the uni-directional rotating bezel, protective patented antishock movement mount and automatic helium escape valve. The robust 43mm dive watch with an impressive 500m water resistance houses a chronometer rated movement complete with a 42 hour power reserve, all housed within a ‘Jet’ black DLC finished Trip-Tick® case with screw in case back.
