Thank you for viewing! ^_^ Watch SAN-100H-7BJR CASIO Sauna Dedicated Watch Black This is a watch for sauna enthusiasts, the "Sauna Watch." It features unique functions and design for safe use in high-temperature and high-humidity environments. 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 moisture resistance, allowing for safe wear in saunas up to 100°C, and the heat-resistant battery makes it difficult for heat to reach the sensitive internal components. 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. *The duration and brightness of the luminous paint's glow vary depending on the intensity and duration of the light it absorbs. *Fogging may occur after entering the sauna and being rapidly cooled, but it is not a malfunction if it disappears within a few minutes. *Please refrain from using it in high-temperature environments other than saunas. Also, even in saunas, please use it for no more than 15 minutes while wearing it on your wrist. #SaunaWatch #SaunaClock #SaunaDedicatedWatch #SaunaGoer
