Casio Ur GWG-100-1AER

Overall, this is probably my favourite G-shock watch so far. The GWG-100 has the most important features of the much more expensive older verion, without the (pointless for most people) compass, barometer and altimeter.
It has the combination of solar power and multiband 6 atomic time synchronisation, which together mean that it should last a lifetime without losing any accuracy.
The white hands on a blacked out background make the watch extemely legible, while the lume pips around the edge of the dial are a big improvement over other blacked-out G-shocks, as they allow easy orientation of the watchface in any lighting conditions.
The UV backlight is really cool, giving a real light show from the different colour glows it produces, and has the added benefit of slightly recharging the lume on the hands, so it can be seen for a while afterwards.
The Lume itself is typical Casio, in that it glows brightly, but does not last long, so the backlight is very useful. It also separately lights the LCDs, so they are clearly visible in the dark.
This is a big watch, but it sits nicely on the wrist, and is very lightweight and comfortable for me.

great watch, super light , accurate, tough, comfortable, easy to read watch face not too heavy looks great. Unfortunately the instruction book is garbage and I have no idea what RCVD means. Ignore all and just leave in the sun and it sets itself
