HOT ! Casio SAN-100H-7BJR Sauna Watch

📄 Product Description

Introducing the Casio SAN-100H-7BJR, a uniquely designed Sauna Watch made exclusively for sauna enthusiasts. This innovative model from the Casio Collection is built to perform safely and reliably in high-temperature, high-humidity environments — perfect for those who enjoy long, relaxing sauna sessions.

Switch effortlessly between Sauna Mode and Regular Time Mode with a single button. The 12-minute sauna timer helps you keep track of your session with ease, while the luminous hands ensure visibility even in dimly lit sauna rooms.

Built with heat- and moisture-resistant materials, the SAN-100H-7BJR is safe to wear in saunas up to 100°C for up to 15 minutes. The resin case and band prevent burns, while internal components are designed to minimize heat transfer and prevent fogging. The curled band, inspired by traditional sauna locker keys, gives it a stylish yet practical look suitable for both sauna and daily use.
