The solar ones are good for summer, but during winter I had to leave mine basking in the sun because it normally never got any rays hidden beneath the winterly clothes; but the Kinetic is always charged up to full.
I used to have one of the first Kinetic's, I got the one with silicone band... big mistake. The stupid band would only last 2-3 weeks max for me, I ended up paying the full price of the watch again in 'blue' silicone bands lol
atleast the texture was unique
@fkusumot: How many watches do you have? Bet you got loads, one for every day of the month.
