Dress meets Tech in the New Oceanus 3 analog radio-controlled watch. The convenience of a light powered watch, combined with the incredible accuracy of atomic timekeeping. Oceanus watches receive radio signals from the most accurate clock in the world - the cesium atomic clock at the National Bureau of Standards, which is accurate to 1 second in a million years

• Light Powered - No batteries to change, ever! Will hold a charge and run for up to 4 months with no additional light exposure. When stored in the dark, the power save function will keep its charge for over a year.
• Shock Resistant
• 100 meter water resistant
• Your watch will communicate by radio every day with the US atomic clock, insuring accuracy to the split-second and automatically adjusting for daylight savings time and leap year.
• Two high-intensity LEDs make the face of your Oceanus easy to read, even in total darkness. You can turn on the illumination manually, by pressing a button. It also has an autolight that can be set to automatically light the LEDs when you tilt the watch toward your face
• Oceanus watches have a Sapphire Crystal, the most valuable and scratch resistant glass crystal available
• Magnified date display with automatic perpetual calendar (after all, it is checking in with the atomice clock, so it will automatically know the number of days in each month, even leap year.)
• Alarm
• Push-button folding safety clasp
• If you happen to be outside the signal area (such as when travelling outside the US) this watch will still function just like a good quality quartz watch, with a tolerance of +/- 20 seconds per month.
• Width of case 42mm (about 1 5/8 inches wide)
