1. Do they run completely off of solar power, or do they still require some sort of battery to work?
2. How long does the charge last before you need to venture out into the sun again?
3. How much do they run for these days? (price I mean)
I'm just curious as I wear my CompuChron LED watch all the time and it runs off of two batteries. I was told by my Father that they would last about a month possibly.
I'm just curious because I love the watch I have, but if it is more cost-effective to get a solar powered LED watch... well you know.
Some of the other forum members will be able to give you more of an indepth answer but to start the ball rolling........
The first watch on the left is a Synchronar which use a solar panel to continually recharge two sealed batteries - The batteries should keep charged with normal wear, they will only lose their charge if they are left in a dark place (like a drawer) for a good number of weeks.
The price (eBay) has been steadily falling over the last year or so and working examples (reconditioned) have been selling for around the £500 mark.
The batteries in the Compuchron should be good for around 12 months - depending on usage. Silver oxide batteries last a little longer although they are slightly more expensive to buy.
