CASIO Sauna Watch SAN-100H-1BJR

Product Overview

The CASIO SAN-100H-1BJR Sauna Watch is a purpose-designed analog watch for sauna use, featuring a dedicated 12-minute sauna timer and a heat-resistant design for saunas with temperatures up to 100°C.

The sauna mode can be switched from the standard time display with a single button, allowing elapsed sauna time to be checked easily using the analog hands. The simple dial and luminous hands are designed to make the time easier to see in low-light sauna environments.

The watch uses resin exterior components and a case structure designed to help reduce heat-related discomfort during use. Its moisture-resistant construction also helps reduce internal fogging caused by humidity. The lightweight resin band uses a curl-style design for easy attachment and removal.
