I have a womens Columbia watch that is also water resistance to 65 meters. The battery has gone dead and I would like to replace it. Most watches have a groove to pry the cap off. This watch does not have that. Must the cap be turned and by a special tool or can you give me an idea on how to this. I did not want to scratch or ruin the watch. Thanks Traudl Renner

Your watch is water resistant to 50 metres. There should be a wave symbol etched in to the back of the case.

WARNING: TO MAINTAIN WATER-RESISTANCE, DO NOT PRESS ANY BUTTONS OR PULL OUT THE CROWN UNDER WATER UNLESS YOUR WATCH IS INDICATED AS 200 METER WATERRESISTANT.

The most common failure of a watch to be water resistant is caused by a faulty contact between the case at an opening around the glass, crown, or pushbutton and the opening's gasket. Worn or defective rubber O-rings are often a cause of failure. Condensation forming under the crystal of a watch following a sharp temperature change (a swim after a stretch in the sun, for example) tells you to have the watch checked without delay. This can be an indication of additional moisture elsewhere inside the case. It is also the only water-tightness check a consumer can perform.
Of course non-water-resistant watches don't contain the additional seals and gaskets found on water-resistant models. Consequently, moisture-laden air can easily enter the case. Once inside, a pronounced change in temperature may cause condensation to form under the crystal. Very little can be done to prevent this. A high-quality water-resistant watch, however, properly serviced and maintained, will be sealed to prevent internal water damage and will more than outlast an ordinary watch.
To keep the watch properly sealed, replace any defective parts , such as gaskets, crystals, and crowns. Water-resistant watches should be tested for case tightness at least once a year, as well as every time the watch is opened, such as when a battery is replaced.

To be honest, I would send back to Columbia. Water resistant watches are not only tricky, but you risk losing the warranty on your watch as well.
I would go to link and follow instructions:

mcdevito 75 here, Usually 50--100 meters of water resistance on brand new watches. However after a battery change, unless you also change the gasket (rubber ring) on the cover, you could loose all water resistance capability.

Best bet is to start by replacing the battery. At 8 months it'll be due for one soon anyway and a new battery may "reboot" it so it runs again. As a battery wears out it doesn't just stop, it may still maintain the display even though it stops keeping time. Also, new "e-ink" displays require no power to maintain the display 0 only to change it.

To get a set of instructions, go to their web site (/www.columbia.com).

In the search box at the top right of the page insert "watches" and you will see in the center a picture of a watch, select "PDF......." and the watch manual will appear, choose the one that similar to yours.

Most makers recommend that you take it to a watch shop. As you correctly suggest, the seal is important abd might be betterleft to the professionals.

There are a few possible reasons why your watch is not working:

1. The battery is dead (sometimes even new watches have a dead battery in them).
2. The plastic piece between the crown and the watch case was not removed (this protects the battery from wearing down until you receive the watch).
3. You bought a watch with a damaged movement and it just will not work period so you may have to return it, exchange it, or have it repaired

These are the 3 reasons why your watch could not be working. The reason will fall into one of these 3 categories, so I hope this helps!
