Synthetic sapphire crystal

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. Water resistant up to 100 meters, or about 330 feet.On top of being a functional, sturdy, and a nice looking timepiece, the Oceanus 5 Motor is exceedingly comfortable. I've been wearing it for several days now, and it has a way of *** you forget it's there. Although I've found that the luminosity does last all night (this was easy to test because between kids, earthquakes, and general city cacophony, I'm awakened at all hours of the night), I wouldn't mind seeing the 5 Motor outfitted with the same LED illumination system as the Oceanus Chronograph. The 5 motor is also not the easiest watch to get the hang of. I'm a watch geek, so I picked it up pretty quickly, but for some, there will be a fairly steep learning curve.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. Tachometer. Titanium case and bracelet (also available with a black leather strap) . Fortunately, there's a little cheat sheet etched in the back of the case next to the pushers in the form of ALM (alarm), WT (world time), ADJ (adjust), and CHR (chronograph) to remind you which buttons do what, so you can always refresh your memory while standing in line at the DMV.The Oceanus 5 Motor retails for $580 MSRP, and can be purchased at several retail outlets, and here and there online.
