Casio watches are highly reliable and trustworthy timepieces that can endure any trying conditions. The majority of the brand’s watches are water resistant and will survive small amounts of shocks that might otherwise rattle other watches. They also come with a fantastic battery life. Casio was one of the earliest adopters and manufactures of watches with quartz movements and some of its current models promise up to 10 years of battery life. Beyond the functional appeal, Casio watches are a fashion statement. Celebrities like Bill Gates, Serena Williams or Dwayne Johnson have all been spotted wearing timepieces from Casio.
