Seiko Solar Watches Reviewed: How Well Do They Stack Up?

NanaDC watch reviews

Solar-powered watches have become the norm among most brands and watch fans.

Watches such as the Citizen Eco-Drive or Casio G-Shock series possess maximum solar energy for their battery life.

Seiko is another player in the solar watch game. The Japan-based watch manufacturer has recently ventured out in creating solar-powered watches.

Seiko solar watches still offer the brand's aesthetic appeal, but with more enhanced power reserve settings from light sources and superior timekeeping.
