The Sa Watch is a watch specially designed for sauna enthusiasts. Its unique features and design ensure safe use in hot and humid environments. Switch between sauna mode and regular time mode with a single button. Even those who tend to forget the time during their sauna session can easily use the 12-minute timer in sauna mode. The watch features a simple dial and luminous hands for easy readability in dark sauna rooms. This allows you to read the time on your wrist, even in saunas where it can be difficult to read. The Sa Watch is heat- and moisture-resistant, making it safe to wear in saunas below 100°C. It uses a heat-resistant battery that can withstand high temperatures, and its heat-sensitive internal components are designed to prevent heat transfer. The exterior components are constructed of resin to prevent burns, and the only metal screw is designed to avoid contact with the skin. The moisture-resistant resin material prevents the interior of the watch from fogging up. The distinctive and eye-catching style, featuring a curled band inspired by sauna locker keys, makes it a subtle sauna-inspired accessory for everyday life. In addition, the simple, functional button layout allows for a stress-free, comfortable, and convenient sauna experience. * The glow-in-the-dark paint's glow duration and brightness vary depending on the intensity and duration of light absorbed. * The watch may become cloudy if it is suddenly cooled after a sauna session. However, this is not a malfunction if the glow disappears within a few minutes. * Please refrain from using the watch in high-temperature environments other than saunas. Even in saunas, please wear the watch on your wrist for no more than 15 minutes. ● 5 ATM water resistance ● Usable environment: Saunas up to a set temperature of 100°C (wear on the wrist for no more than 15 minutes) ● 12-minute timer ● Approximately 5-year battery life * Battery life is calculated from the time of manufacture due to the monitor battery. ● Monthly accuracy (room temperature accuracy): ±15 seconds ● Battery used: BR1225A ● Battery life calculation: Sauna: 3 times/day (Normal time mode: 23 hours, Sauna mode: 1 hour)
