Is a Tough Solar Watch Really Better Value Than a Battery Watch?

How Tough Solar works

A solar cell under the dial converts light — both sunlight and indoor lighting — into energy stored in a built-in rechargeable battery, so you don't need battery changes like a regular watch.

Advantages of solar

• check_circleNo regular battery changes, so it costs less over time
• check_circleGreat for forgetful people or anyone who doesn't want trips to the shop
• check_circleMany models keep a charge for months even without light

Things to note

The starting price is usually a little higher than a battery model, and if you keep it in the dark for a long time without wearing it, the built-in battery can run down (put it in the light and it starts working again). The rechargeable battery itself lasts many years with proper care.

Summary: who it suits

If you don't want to deal with battery changes and wear your watch every day, solar is worth it in the long run. See solar models in the EDIFICE and G-SHOCK lines.
