For those with a diving license, we recommend a watch that is waterproof up to 300m.
This level of waterproofing makes it suitable for diving and various other marine sports.
There is now a wide variety of diver's models available, with many different brands producing watches that are water resistant to 300m.

Unlike typical skin diving or scuba diving, this dive involves using helium gas instead of nitrogen to saturate the human body. This watch boasts the ultimate in professional waterproofing, surpassing even the limits of air diving! Seiko's cutting-edge technology will move any man's heart!
