CASIO Sauna Watch SAN-100H-7BJR Brand new, unopened Orange This is a wristwatch for sauna enthusiasts, the "Sauna Watch." It features unique functions and design for safe use in high heat and humidity. You can switch between sauna mode and normal time mode with a single button. Even those who lose track of time in the sauna can easily use the 12-minute timer in sauna mode. Also, the simple dial and hands coated with luminous paint allow you to check the time even in a dark sauna room. It has heat and humidity resistance and can be worn safely in saunas up to 100°C. The heat-resistant battery prevents heat from reaching the internal components, which are sensitive to temperature. The exterior parts use resin to avoid burns, and the only metal screw is designed not to touch the skin. Resin that is resistant to moisture is used to prevent the inside of the watch from fogging up. The curl band, inspired by sauna locker keys, allows you to subtly feel the sauna even in everyday life.
