Oceanus is the first watch to offer 5 motor technology combined with Atomic Solar technology. Each motor controls a movement on the watch face (second hand, chronograph, world time, and 24 hour time). The new fifth motor replaces the function of the LCD screen found in their first generation models with a classic date display. It boasts most of the features of the Oceanus Chronograph, but without the LCD in the 3 o’clock position. The downside of removing the LCD is that the watch gets slightly more complicated.
The latest addition to the Casio Oceanus lineup is the OCWM800TBA-1A, the world’s first atomic solar powered chronograph. The Casio Oceanus line is known for its Multi-Band 5 Atomic Timekeeping, which guarantees precise and reliable timekeeping by receiving radio time calibration signals from US, UK, Germany and Japan. These timepieces also boast Tough Solar Power, which fuels the battery with light from the sun as well as indoor sources, eliminating any worries of losing track of time. All 5 motor models come in Titanium cases along with Titanium or Leather bands. As with all Oceanus models, they are built with style, functionality and technology in mind.
Features of the Oceanus 5 Motor include:
- Atomic timekeeping. The Oceanus watches will pick up time calibration signals transmitted in the US (Fort Collins, CO) and Japan. It will try to calibrate up to six times per day at predefined times during the wee hours of the morning, and the watch can also be placed in calibration mode manually. If you’re in an area where you can’t receive a time calibration signal, Oceanus watches can also be set manually.
- Solar powered. All Oceanus watches have solar cells which recharge batteries capable of keeping them running for up to five months when fully charged. The Oceanus 5 Motor has a low power indicator to let you know when you haven’t been spending enough time in the sun.
- World time. The subdial between the 2 and 3 o’clock positions is a 24-hour dial with both hour and minute hands to display the time in 27 cities (29 different time zones). 30 different time zone options expressed as either city abbreviations or GMT offsets are printed around the perimeter of the dial, and switching between them is as easy as pushing the lower right-hand button (the chronograph’s second hand moves to the currently selected city). Since the world time feature uses a subdial, when the watch is in world time mode, you can actually see the time in both your home time zone, and in the secondary time zone simultaneously.
- Time transfer function. The time transfer function allows you to swap time zones between your home time zone and the watch’s secondary time zone. For instance, if your home time zone is LAX and your secondary time zone is Tokyo, and you travel to Tokyo, you can easily reverse your home and secondary time zones so that your home time zone is Tokyo, and your secondary time zone is LAX. When you head home, just invert them again.
- Chronograph. The Oceanus 5 Motor has a stopwatch with a resolution of 1/20th of a second, capable of measuring elapsed times up to 23 hours, 59 minutes, and 59.95 seconds. The stopwatch’s second hand is the third primary hand (which is usually the second hand on analog watches without chronographs), and the subdial at the six o’clock position which normally measures seconds in timekeeping mode measures fractions of a second in chronograph mode (only for the first 60 seconds).
- Daily alarm. When in alarm mode, the world time subdial allows you to set a single daily alarm.
- Automatic calendar (through the year 2099)
- 24-hour subdial at the 9 o’clock position
- Synthetic sapphire crystal. A sapphire crystal (virtually scratch-proof) is not something you see everyday on a Casio, but on an Oceanus, it’s standard.
- Approx. battery life: 5 months on full charge (without further exposure to light)
- Battery Power Indicator
- Water resistant up to 100 meters, or about 330 feet
- 47.3mm case / 99gm total weight
