Understanding Watch Water Resistance

Another fine post from the watch doctor.

Water Resistance in Watches

Perhaps it says it on the back of your watch. Or maybe it’s written in small text on the face.

We’re talking, of course, about a watch’s water resistance. Water is necessary for many things to run smoothly, like humans and plants. But when watches and water mix, the results can vary and lead to one unhappy — albeit busy — watchmaker.

So what is water resistance?...

  The deeper you go under water the greater the pressure on the seals of the watch. My Pulsar is good to about 3 Meters. Some watches will say something like 2 Meters for 30 minuets and other watches are only good for a heavy rain or washing your hands.

I thought this table would be very helpful in making choices:



  The deeper you go under water the greater the pressure on the seals of the watch.

The Russians really figured it out with the vostok amphibia.  They use the increasing pressure to dynamically improve the sealing of the watch.
