Some people want to buy automatic watches for formal events and even casual affairs while there are people that are more inclined to buy a water-resistant watch instead. Water-resistant watches are perfect for active people since they are going to sweat a lot and some would use it for diving and snorkeling excursions. Now, if you are planning to buy a water-resistant watch for yourself, you might be tempted to try its water-resistance rating for yourself. Today, I am going to tell you how you can safely test your watch’s water-resistance at home without damaging your timepiece.


Water-Resistant Watches: What Are They?

A water-resistant watch is a timepiece that can come in contact with water but only up to a certain extent. For instance, if you find a certain water-resistance rating either at the front or the back of the watch, you might find that it is water-resistant up to XX meters or ATM or BAR. Such a rating is given by the manufacturer and is tested for veracity by the ISO. The rating is based on three factors, namely the case back/gaskets, the crown, and the case and how well it can keep water at bay. Do keep in mind that the components of the watch itself- for instance, the gaskets- may age and its water-resistance may also decrease as a result. Testing your watch from time to time will ensure if it is still safe to use at the same level as you did the first time you bought it.

As for the rating, the watch manufacturer may either use meters, ATM (atmosphere), or BAR (same as ATM). Each bar is equivalent to 10 meters, so a 5 BAR watch can be water-resistant up to 50 meters. That being said, what do all of these ratings mean? Well, here are some general estimates:

  • 30 Meters- Generally only splash-proof
  • 50 Meters- Generally okay to be wearing while taking a shower and some light swimming, but is not appropriate to use in scuba excursions or deep diving activities
  • 100 Meters- Used mainly by triathletes, it can withstand water pressure, albeit you still do not want to use it in deep diving sessions
  • 200 Meters- If the watch is rated to last at least 200 meters and above, it is okay to use for deep diving.

Is Fogging a Sign of Leakage?

Not necessarily. Moisture or fogging in a watch is actually just a result of some light liquid that will eventually just dry out once it is cooled down. However, if water is visible on the watch face itself, it may be a sign of leakage and must be serviced immediately. Testing the Water-Resistance of the Watch For 30-50-Meter Water Resistance watches, you can take a shower and see if there is any fogging or visible liquid on the watch face. For 100-meter water-resistant watches, take a swim on the beach or the pool but do not go deep underwater. For 200-300-meter or above ratings, take a scuba-diving session for at least 10 minutes.
