Box and papers. A contender for ‘Most dangerous underwater job' has to be that of the Royal Navy Clearance Diver. The British Navy is one of only three in the world to employ these ‘Human Minesweepers', highly trained individuals whose initial role was to clear sea-lanes to allow landing craft to approach enemy beaches safely. If underwater bomb disposal isn't enough, these divers are used in military salvage operations, retrieving bodies, equipment and ordnance as well as a multitude of other hazardous operations. In 2013 a limited edition of 50 watches was created to celebrate 60 years of the unit.
