Oris' 'Aquis Whale Shark' reference is a testament to the watchmaker's longstanding commitment to protecting the world's oceans and their ecosystems - it's produced in a limited run of 2016 to mark the year of the International Union for Conservation of Nature's whale shark preservation announcement. It has a robust stainless steel bracelet and 43.5mm case, housing a textured blue dial with a date window and an orange 24-hour GMT hand that can keep track of two time-zones in concert with the rotating 24-hour bezel. A whale shark - the sea's ""gentle giant"" - is fittingly engraved on the case back.
