Уважаемый Dipol,
Я как раз не делал никаких выводов -- потому что не могу их сделать. Поэтому и написал в форум -- чтобы почитать выводы других...
Я посмотрел линк, который Вы дали. Я видел такую информацию и раньше -- проблема, однако, в том, что источник этой информации неизвестен. Например, вот по этому линку приведена другая - противоречащая Вашей - информация (для плавания - начиная со 100 м, а не с 50 м):

What does the water resistance rating really mean?
Water resistance is normally expressed in meters. This rating is only theoretical and refers to the depth that a watch will keep water out if the watch and water are both motionless. These conditions never really exist in real life because the users arm movement dramatically increases the pressure on the watch, along with the water moving itself. The chart below should help you understand how deep you can really go with your watch.
Measurement Units: 1 meter is about 3.3 feet / 1 ATM (atmosphere) or bar is 10 meters
If a watch is labeled only "water-resistant." It can withstand splashes of water but should not be submerged in any water.
50 meters: suitable for brief water exposure
100 meters: suitable for standard swimming pools
200 meters: suitable for recreational scuba diving
1,000 meters: (roughly three-fifths of a mile).

А вот, например, информация с сайта американского Сейко:

Water Resistant These watches have withstood testing to depths of 24 to 30 meters (100 feet) and will tolerate splashes of water or rain, but should not be worn while bathing, showering, washing dishes, swimming or diving. Watches with this designation will have the words Water Resistant engraved on the caseback.
Water tested to 50 meters (165 feet) Okay for showering, bathing, dishwashing and swimming in shallow water. Not while snorkeling or scuba diving. The designation engraved on the caseback will be Water Resistant 5 BAR (BAR is a European equivalent of the international measurement ATM, or "atmospheres." To calculate the water-tested depth in meters, multiply the BAR number by 10.)
Water tested to 100 meters (330 feet) These watches are suitable for swimming and snorkeling, but not scuba diving. The caseback designation will read Water Resistant 10 BAR.
Water-tested to 150 meters (500 feet) These watches can be worn for general water sports, including snorkeling. The caseback designation is Water Resistant 15 BAR.
Информация тоже довольно темная -- толком неясно, чем отличается 100 м от 150 м, и даже 50 м от 100 м.
А у некоторых производителей бывает еще и 60 м.[/quote]
