Casio SAN-100H: the sauna watch for extreme heat and humidity

Casio presents a watch designed for dry and humid heat: the SAN-100H. The idea comes in response to growing use in spas and hammams.

What’s more, Casio targets a public that wants a simple tool. In this context, the brand is targeting regulars who time their passages. In Japan, the guide price is JPY 16,500.

Why a “sauna watch” now?

Many are looking for a reliable benchmark to manage hot-cold cycles. A dedicated watch reassures beginners and structures their routine. Smartphones, on the other hand, remain ill-suited to these conditions.

The proposal emphasizes clarity and durability. Casio talks about sauna use, without getting lost in gadgets. Also, the SAN-100H-1BJR and SAN-100H-7BJR variants cover sober tastes.

“A simple watch, cut for the heat, is enough to reassure and set the pace for the session.”

Design, legibility and advertised uses

The dial must remain legible despite fog and hot light. So, strong markers and a clear display make sense. Casio’s approach is utilitarian, designed for the present moment.

Basic functions are expected: countdown, alarm and stopwatch. However, the central promise remains heat and humidity resistance. Casio also seems to prefer easy-to-handle controls.

• Set a session alert without leaving the sauna
• Read the time at a glance in a warm lighting environment
• Reduce handling thanks to simple settings
• Sober variants for mixed use
• Accessible Japanese trial rates

What we know, what we need to check

What’s public can be summed up in a few very concrete lines. The name SAN-100H and the sauna orientation are indicated for the Japanese market. Casio references at least two finishes, black and white. The announced price is around 16,500 JPY.

Key parameters still need to be confirmed in the store or on the data sheet. For example, the temperature range supported and steam management. In addition, Casio will have to specify the warranty for sauna and cold bath use.

The bracelet’s comfort will count in humid and salty environments. A soft texture avoids irritation on warm skin. In short, a secure buckle and simple maintenance will make all the difference.

Responsible purchasing guide

I did not receive the content of the lepetitpoussoir.fr article concerning the Casio SAN-100H to extract the references.
However, other sources mention the SAN-100H-1BJR (Black) and SAN-100H-7BJR (White) versions, at a guide price of JPY 16,500.

Before you buy, check the possible return after an initial test. Also, check readability in a warm, damp room. Casio often publishes user guides, which should be read without haste. This will help you avoid mistakes and unrealistic expectations.

For whom, and how to use it safely?

This model is aimed at regular sauna users and the curious. For everyday use, Casio’s SAN-100H is discreet and practical. A single tool can be used for both relaxation and training.

Set reasonable goals based on your tolerance and condition. Therefore, use the timer as a reminder, not a challenge. However, get out at the first sign of discomfort. Also, hydrate before and after each session.

After the session, rinse the watch with fresh water and dry it. On the other hand, avoid placing it near a source of heat. Casio recommends that you regularly check the seals and bracelet. What’s more, minimal maintenance extends the watch’s lifespan effortlessly.
