OLLECH & WAJS OW Ocean Graph

All about the OLLECH & WAJS OW Ocean Graph

The OLLECH & WAJS OW Ocean Graph is a homage to the Ocean Graph by Ollech & Wajs from 1968 and to all diving watches in the highly regarded “Precision” line. These watches featured patented decompression bezels - an essential safety tool for any diver venturing into deep waters. The modern OW Ocean Graph's color scheme and its bold triangular markings are inspired by the distinctive graphic elements of the historic OW references.

The OLLECH & WAJS OW Ocean Graph is the product of modern Swiss watchmaking. It is powered by a robust, modified ETA 2824-2 OW5P, adjusted in five positions. The movement's main plate is engraved with "Ollech & Wajs Zurich 1956" and features a rotor made by us that bears the famous OW Propeller Monogram. The movement is housed in a 39.56mm diameter 316L stainless steel case that is punched, machined and brushed in the Swiss Jura.

Estimated delivery time is approximately 3-4 weeks from order date.

The OLLECH & WAJS OW Ocean Graph is a compact diving watch with an extreme water resistance of 1,000 m, tested under a pressure of 120ATM. Its water resistance is ensured by a reinforced case back, a double-walled case, a 5.6 mm thick extra strong, domed sapphire crystal and a special screw-down crown with four seals.

OLLECH & WAJS OW Ocean Graph

Like the original Ocean Graph, it is equipped with a decompression bezel that allows divers to calculate safe ascent times. Its indexes and hands are oversized and coated with orange Super-LumiNova® to enhance readability in poor visibility both above and below water.

The OLLECH & WAJS OW Ocean Graph S version is delivered on the OW S-type Mark II beaded bracelet made of stainless steel. This bracelet was inspired by the Ollech & Wajs models of the 1960s. Its links are individually crafted from a solid block of 316L stainless steel, carefully brushed, assembled and screwed together by hand. This process prevents the usual stretching common to pressed steel bracelets and ensures both durability and comfort. The bracelet's double clasp prevents accidental opening while remaining easy for divers to use.

The OW Ocean Graph also comes with a 20mm, handcrafted, high quality blue Perlon plain strap in the RAF style. Woven exclusively for OW, it is made from high quality, lightweight braided nylon that is highly water, salt and oil resistant. Offering a tactile blend of comfort and durability, the band is finished with a brushed stainless steel buckle signed "OWZ 1956".

The decompression bezel of the new OW Ocean Graph has three concentric zones. The most central zone shows the elapsed dive time from 0 to 60 minutes (A). It also contains information about the maximum diving depth in meters (B). In the central zone, the dive times (C) for which decompression is required are marked, corresponding to the depth indicated in the most central zone (B). The outermost zone of the bezel shows the decompression times in minutes (D) that the diver must maintain at a depth of 3 m, calculated according to the depth (B) and the total duration of the dive (A).
