I checked THIS one out yesterday, from their Aviation line. Somewhat large? Yes: Size of case/total weight -> 54.1 x 52.4 x 16.4mm / 118g Totally over-engineered for anyone except a Navy SEAL, I think: Multi-Band Atomic Timekeeping (US, UK, Germany, Japan, China) Receives time calibration radio signals which keep the displayed time accurate Auto receive function (up to 6 times per day/up to 5 times per day for China) Manual receive function Signal: US WWVB, UK MSF, Germany DCF77, Japan JJY40/JJY60, China BPC Frequency: US 60kHz, UK 60kHz, Germany 77.5kHz, Japan 40/60kHz, BPC 68.5kHz Tough Solar Power Shock Resistant Triple G Resistant Tough Movement Auto hand home position correction 200M Water Resistant Neo-brite luminous hands and markers Thermometer Display range: -10 to 60 C (14 to 140 F) Display unit: 1 C (2 F) World Time 29 times zones (29 cities + UTC), city code display, daylight saving on/off, home city/world time swapping) Beeper Alarm 1/20 second chronograph Measuring capacity: 1:59'59.95" Measuring modes: Elapsed time Other: Fly back Countdown Timer Measuring unit: 1 second Countdown range: 60 minutes Countdown start time setting range: 1 to 60 minutes (1-minute increments) Full Auto-Calendar (pre-programmed until the year 2099) Day/Date Display 12/24 Hour Formats Accuracy: +/- 15 seconds per month (with no signal calibration) Storage Battery: Solar Rechargeable Battery Low Battery Warning Power Saving Function Approx. Battery Life: 6 months on full charge (without further exposure to light) Module: 5240 (Although that thermometer could come in handy if one of my daughters was running a fever...) Already one of their higher priced models at $600: http://www.gshock.com/watches/Aviation/GWA1000FC-2A I think this is just a passing fancy on my part, so I will continue to investigate and check out the wares but the fact that I haven't pulled the trigger given the price point and after seeing one on my wrist (and it ain't half bad either) probably - fingers crossed - means I will do without it. Whooooooooooooooooooooooa!!!!
