CASIO Collection SAN-100H-7BJR Unisex Watch White (Japan Model)
Product Description
Discover the Casio Sa-Dokei, a wristwatch engineered specifically for sauna enthusiasts. Designed to perform reliably in hot, humid environments up to 100°C, it features 5-bar water resistance and heat-resistant construction so you can enjoy your sauna session with peace of mind. A simple button lets you switch instantly between standard time mode and sauna mode.
The 12-minute sauna timer helps you manage your session effortlessly, while a clean dial and luminous hands keep time easy to read even in a dim sauna room. The heat- and humidity-resistant structure protects internal components from temperature spikes, and the case and band are made from resin to reduce burn risk; the only metal screw is positioned so it does not touch the skin. Moisture-resistant materials also help reduce internal fogging.

The coiled “locker key” style resin band offers a distinctive, playful look that transitions easily from sauna to everyday life, while the simplified button layout keeps operation intuitive and stress-free. Note: Luminous brightness and duration vary depending on light intensity and charging time; brief fogging may occur after rapid cooling and usually clears within a few minutes. Avoid use in non-sauna high-temperature environments and limit continuous use in the sauna to 15 minutes while worn on the wrist.
