Perhaps one of the most charming watches on this list and one of the more popular items available from our shop - the Oris Divers Sixty-Five is a great example of a brand updating a classic design with modern materials and manufacturing techniques; replacing a coated brass casing with stainless steel, and a plexiglass crystal with a more modern sapphire crystal.
If for whatever reason you don't want a Rolex then take a look at the Blancpain Fifty Fathoms Bathyscaphe. It's water resistant to the usual 300m, is a more comfortable 43mm wide (and 13.40mm deep) and even includes a transparent case back, which is a feature less often found on dive watches; though, this may be due to the increased thickness they give a watches case, the perceived weakness that they give and the additional cost involved.
This mountainous 47mm wide Oris is truly gigantic in size at a whopping 47mm wide and has a substantial 17.7mm case depth. It is not only Oris's first watch of its kind; but, 'the world's first automatic watch with a mechanical altimeter'.
This watch is currently my absolute favourite Oris watch at the moment (at the time of writing). It holds a design that has tried the tests of time and succeeded. This watch was originally constructed in, as you may have guessed ,1965. luckily when Oris relaunched this updated version they didn't kill what made it so special; but, improved on it with modern manufacturing techniques and new materials.
