The Seiko Blue Monster

Moving from right to left, it indicates local tide height based on latitude and the intertidal interval. Since tides vary with local geography, you can calibrate the watch to match your local cycle. This Oceanus (which I'll call the 5 Motor Tide Graph) is similar to the OCW600TDA-1AV previously reviewed, however the 5 Motor Tide Graph seems a little more geared toward the worldwide business traveler; not only can it receive atomic time calibration signals in the US, but also in Japan, Germany, and England.The feature of the Oceanus 5 Motor Tide Graph that I find most interesting is, well, It sounds complicated, but once you understand it and see it work, it's pretty intuitive, and even a little addictive.Seiko seems to be well aware of the effect Kinetic movements have on us as they refer to their new Direct Drive as "emotional technology" the tide graph. At the top of the multi-function dial at the 3 o'clock position is a small tide chart. The solar panel is actually a ring around the dial, in a complimentary shade of silicon-chip blue.What sort of globe-trotting person needs a tide graph? My personal theory is new managers who still surf, sail, or dive. 5-band radio reception.100M (330 feet) of water resistance.World time with time zone swapping (easily swap your primary time zone with your secondary time zone, and vice versa).Subtle date at the 4:30 position (nicely unobtrusive, but there when you need it).Retrograde day indicator in addition to the date.
