※Due to a high number of cancellations, we are unable to accept payment via convenience store. This is the "Sa-dokei" wristwatch, designed for sauna enthusiasts. It features unique functions and design for safe use in high-temperature and high-humidity environments. Brand new, unused. We will ship promptly once preparations are complete! 【Product Features】 Switch between sauna mode and normal time mode with the touch of a button. Even those who lose track of time in the sauna can easily use the 12-minute timer in sauna mode. 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, allowing for safe use in saunas below 100°C. The heat-resistant battery prevents heat from reaching 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 fogging inside the watch. The curl band, inspired by sauna locker keys, allows you to subtly feel the sauna even in everyday life. Thank you. - Model: SAN-100H-1BJR
