Review of the Casio GW
You can turn the auto repeat functionoff in which case, the left-most LCD (the one at the 9 o'clock position) displays1/10 seconds rather than the number of times the timer has repeated.Stopwatch. Measure elapsed time, split times, and two finishes up to 99:59':99".Electro-luminescent backlight. That means only the LCDs are illuminated, notthe entire face of the watch. This watch also has an auto illumination functionwhich means, when activated, it will illuminate automatically if you hold thewatch parallel to the ground, then rotate it more than 40 degrees toward you***ce. It's even smart enough not to activate itself if it senses that there'senough light in the room that you shouldn't need it. Pretty slick.Water resistant. 20 BAR (20 ATM, 200 meters, or 600 feet).Shock resistant. According to the manual, "The watch can beworn on the wrist during any hard sports. (Use care not to allow the front glassto butt against any hard objects.)" Although they don't specify, it should beok to wear during "soft sports," as well. Scratch-resistant mineral crystal.Accurate up to about 15 seconds per month. Not exactly anengineering marvel, but consider this: 15 seconds per month is roughly .5 secondsper day (worse case scenario), so if the watch calibrates nightly, at any giventime, it should never be more than a half second off, and most likely much lessthan that. Not bad.It chooseslate night/early morning with the assumption you are asleep, and the watchis sitting peacefully beside you, dutifully facing Fort Collins near a window.The watch also records the date and time of its last successful calibration,so don't worry about trying to stay awake to monitor it's progress.Signal strength indicator. Very handy for finding the optimal spot to letyour watch soak up the time calibration rays.Analog and digital time synchronization. This means thatthe hands on this watch are actually just an analog representation of the digitaltime. This may seem obvious, but Casio actually makes analog/digital watcheswhere this is not the case. You canset the analog hands to be inconsistent with the digital time, but theywill still be in-sync, just with an offset between them. I have another analog/digitalG-Shock that arrived with the hands way off for some reason, but it was quiteeasy to get them synchronized, and they have stayed in-step ever since.World time. 30 cities (29 different time zones) around the world.Five alarms. Each is an independent daily alarm. Nothing special,except that there are five of them. Naturally, there's an hourly time signal,as well.Auto-repeating countdown timer. 60 minutes is the timer'sceiling, and it repeats up to nine times.
