Class 170

The Casio W 800H convinces with a simplicity and a 10-year battery. The clock is "100m water resistant", so you can start the clock when taking a shower or washing your hands. The wristband is soft, flexible and comfortable to wear. The lighting is sufficient. I am very pleased with the clock.

At Annex 3 years later:
The clock still works perfectly. The traces are minimal, although worn day and night.
