I got the GW-002E-1VER 2 years ago. It is Waveceptor and solar power and is quite simply awesome. It cost me £34 from Amazon.
In ‘normal’ use, under jackets, long sleeve tops etc. (rarely shirts)- using the light on a not infrequent basis, I’ve never seen the battery indicator less than ‘High’. I’ve found the Waveceptor function to be flawless. Never had a problem getting a signal anywhere in the UK, anywhere in the house. I now have a watch which I never have to worry about, and I know is to-the-second accurate.
Took it to Europe (Amsterdam) and it worked fine. In the USA it admittedly didn’t get a signal, but it didn’t lose any time over the week we were there.
