Watertight Guide (Waterproof Watches)
The watertightness of the watches is marked "Water Resistant" or "Water Proof", followed by its unit of measurement. The units used are:
FT or feet
Here is a simple guide to ratios between units of measurement. The ratios are not accurate.
1 bar = 1 ATM = 10m = 33FT or feet
The waterproof indicator is usually written on the back of the watch, on the case cover or inside the dial.
Caution is required when the watch is not labeled, meaning it DOES NOT come into contact with water, as there is a serious risk of it being destroyed.
