OMEGA has revived its Ploprof name with four new editions. Long regarded as OMEGA's most water-resistant divers' watch, the Ploprof is known to not only survive, but also perform, under the crushing pressures of the ocean — a feat since 1970.

The new models are built from titanium, which are around 40 percent lighter than stainless steel and more resistant to corrosion, while the Super LumiNova tech has been added to illuminate the watch in dark conditions.

The first new model has a blue lacquered dial with a case that is combined with 18K Sedna gold on the bezel, crown and security pusher, as well as the hands and index.

Finally, a darker model of the Ploprof features a lacquered black dial, polished black ceramic bezel ring and the same orange aluminium and varnished white hands as the previous model.
