Hi. Ive been thinking of getting one of the solar powered wave ceptors from ebay. At first I was looking on this site for any pictures of the prg 50, to see how big it is on the wrist. While at the same time looking for info on the waveceptors. Then I read all these reports of the dodgy CTL 1616 battery. Should I reconsider buying any watch with this battery in. And just as a sideline. Can you replace this battery with a non recharging battery?
