This one is a limited edition of 2,016 pieces, has a 42 hour power reserve and striking, almost skin-like dial finish. The Whale Shark edition from Oris is a novel twist on their Aquis dive model, with a GMT function to boot. It’s just over 43mm wide, with plenty of lume on the dial and at 300m depth resistance it’s a genuine dive watch.

Not cheap at £2250 or so, but a percentage of the cost is supporting Oris in its work to highlight the need to conserve the whale shark, which plays a vital part in the ocean eco-system.

We absolutely love that teal coloured dial, very reminiscent of a Seiko or Zelos dive watch. Therein lies the problem, because a beautiful Zelos Swordfish, with 300m depth rating is just $500. OK it has a Seiko auto movement inside, but as an alternative, it offers you dive ability plus a chunk of change left over to put in your grail watch fund.

You could buy a teal dial Oris Aquis without the GMT function and fancy dial finish for £1600. Always that option.

But then, maybe the Aquis Whale Shark is that grail watch for you? More here at the Jura watches site. Nope, we aren’t commission.
