Eco-Friendly Solar Watch?

There are many eco-friendly solar watches on the market now, but I have found out that they are all very expensive ones like Citizen, Casio, and others of the sort. Well, I was able to find a solar watch that gave me an affordable price tag. It is the Bijoux Terner. It is one of those watches that trying to just purchase one, is near impossible to do, and the only way to get one is to go through an actual retailer who sells them individually. Otherwise, you have to go to the home site and order a pallet worth.
