Casio has expanded the availability of its Sadokei Sauna Watch, which was initially launched in 2024 and became available in the US in 2026, to several European countries. The watch, which retails for €99.990, is now purchasable in the Netherlands, France, and Italy through the Casio store. It is designed specifically for sauna use, capable of withstanding high temperatures up to 100°C (212°F) and high humidity levels. The Sadokei model features two analog hands for timekeeping, accurate to within 15 seconds monthly, and includes a 12-minute timer operated via the watch's mode and reset buttons. Constructed from low moisture permeability resin, the watch is powered by a BR1225A battery, ensuring durability and longevity, with an expected battery life of approximately five years. Additionally, it is waterproof up to 5 bar and comes with a coiled resin bracelet, making it a practical choice for sauna enthusiasts. However, to purchase the watch, customers must be Casio ID members, which can be obtained for free on the brand's website.
