Introduced in 2019, the OW Ocean Graph pays tribute to the 1968 Ollech & Wajs Ocean-Graph and all the dive watches that formed the highly respected ‘Precision’ line. These watches were equipped with decompression bezels, an essential instrument for the safety of any diver venturing into deep water.

The OW Oceangraph is powered by the robust ETA 2824-2 OW5, adjusted in five positions. The movement is modified with an engraved main plate Ollech & Wajs Zurich 1956, and an OW rotor.

The movement is housed in a 39.56 mm diameter 316L stainless steel case, stamped, machined and brushed in the Swiss Jura. The OW Ocean Graph is a compact diving watch, with a water resistance of 1000 meters, which is tested under a pressure of 120 atm.

Its water tightness is ensured by a reinforced case back, a double-thickness case, a 5.6 mm thick, extra-strong, domed sapphire crystal, and a special screw-down crown with four gaskets.

The Ollech& Wajs OW Ocean Graph is equipped with a decompression bezel allowing divers to calculate decompression times. Its indexes and hands are oversized and covered with orange Super-LumiNova®, for increased readability in low visibility conditions.

The watch is worn on a Perlon nylon strap or a stainless steel bracelet.
