I have had one of these for about 15 years. WWV, Solar and tough as nails. The newer ones even look better, I bought one for my dad that looks like a normal watch. Batteries last about 10 years if you wear short sleeves enough to charge them occasionally. Without a solar charge the battery lasts about 6 months. I have replaced the battery twice, they are about $20 and fairly easy to replace if you are handy and careful. Just watch out for the tiny springs.
