STYLING PHOTOS
HOW TO USE
Let's take a look at the simple functions of the sauna clock.
You can switch between sauna mode (12-minute counter) and time mode with just one push.
Of course, everyone enjoys the sauna in their own way!
FEATURES
1. Create your own sauna time with this 12-minute timer.
Sauna Mode ⇄ Normal Time Mode
Switch between sauna mode and normal time mode with a single button. Even if you forget the time you entered the sauna, you can reset it to 0:00 with a single button, allowing you to enjoy the sauna without worrying about the time in your own cycle.
Sauna-Friendly Dial
The simple dial is easy to read even in the dimly lit sauna, and the hands are coated with luminous paint*. You no longer need to remember the time you entered, and you can enjoy the peace of mind of having your own 12-minute timer at hand.
*The luminous paint's glow duration and brightness vary depending on the intensity and duration of light it absorbs.
2. A watch packed with technology for safe use in sauna environments
Newly designed specifically for saunas
This watch features a new heat-resistant battery that can withstand high temperatures, designed for use in saunas. We've redesigned this watch specifically for saunas, including a structure that prevents heat from being transferred to heat-sensitive internal components.
Attention to detail in exterior components
To avoid burns, we've constructed the exterior using resin components. The only metal screw is designed to prevent contact with the skin. Additionally, by using a new moisture-resistant resin material, the interior of the watch is less likely to fog up*, allowing for safe use even in harsh sauna environments.
*This does not guarantee complete fog-proofing. Fogging may occur if the watch is suddenly cooled after a sauna session. However, if this disappears within a few minutes, it is not a malfunction.
3. A distinctive and catchy design inspired by a locker key
Enjoy your own unique sauna style
The distinctive and catchy design, inspired by the 12-minute timer and locker key familiar to sauna lovers, creates a subtle sauna-like atmosphere in your everyday life.
A button layout focused on simple functionality
By carefully selecting functions and tailoring the button layout and shape to suit this model's specifications, we've created a stress-free, comfortable, and convenient sauna experience.
