The OW OCEAN GRAPH MkII

Editor's Note - James Henderson (the "Henki" of Henki Time is the North American Representative for Ollech & Wajs), so this is just the facts - no opinions.

This is the latest release from Ollech & Wajs, a revised version of the Ocean Graph. Per OW:

Ollech & Wajs proudly introduces the Ocean Graph MkII, the latest evolution of one of the most iconic dive watches in history.

Originally launched in 1968 as a specialised instrument for recreational and professional divers, the Ocean Graph defined a new standard in ocean exploration. The reimagined Ocean Graph MkII fuses contemporary engineering, modern functionality, and the insight of Norwegian freediver Siri Østvold, whose vision helped refine the design for the demands of competitive free diver.

The MKII features an innovative multifunction GMT, Tide Tracking, Top Time & Dive bezel. It combines four different timing systems into one rotating bezel and is the first of its kind:

 - Tide Tracking Function: By aligning the bezel with the time of the last high tide (often set against the hour hand), you can determine when the next high and low tides will occur. This is a handy feature for a variety of ocean sports such as surfing, sailing, fishing, and snorkelling.

 - Top Time (Countdown / Elapsed Time) Function: This utility has been developed specifically for competitive free-divers. “Top Time” is a term used to describe the three-minute countdown a diver has to psychologically and physically prepare for a competition dive. Once T-3:00 minutes has been called by the judge, the diver’s buddy (or the diver themselves in training) will align the bezel’s zero marker with the minute hand, and track elapsed time leading up to the dive.

 - GMT: A 12-hour GMT allows you to track two different time zones at once - ideal for those who travel to compete in the world’s oceans.

 - 20-minute Dive scale: allows divers to record elapsed time precisely during the first 15–20 critical minutes of a dive.
