My F91W-1 has water condensation under the clear display. Even after getting rid of it with silica gel, water still condenses inside. Watch works fine. Is there a permanent fix for it?

Water vapor is getting inside watch and condensing. Need to address any and all seals to make sure that they are air/water tight.

Condensation/water in watch?

A watch with condensation under the glass needs to go to a watchmaker without delay, even if the condensation disappears again after a short time. This is one of the worst things that can happen to a watch. It means that minute quantities of water have penetrated the case but the seals are still tight enough to prevent it from evaporating. What you have on your wrist is in effect a miniature hothouse, where the water condenses at the coolest point. The constant damp atmosphere inside the case is very corrosive and, at worst, can destroy the movement. Without watchmakers knowledge there is no way anyone can dry the watch out and not to damage it, so, rush to your nearest watch repair shop as quick as possible.

I want to remove my quartz movement to dry moisture from inside my watch. How can I remove crown, so that I can remove movement? Watch is old Gruen. Not worth shop repair.

Thanks for contacting FixYa.
It is WAY too risky to remove crown/fixture. Try this instead;
  • Step 2 Lay the watch in a dry place in sunlight and see if the water evaporates on its own. Put a piece of soft, absorbent cloth such as a towel under the watch. If the water inside the watch face is only a fine film of condensation that clears on its own after a short time, you probably do not need to do anything else.
  • Step 3 Seal the watch in a plastic bag filled with unopened packets of silica gel desiccant. These are the packets that come in shoe boxes and other packaged items. You can also use dry rice instead of the silica gel packets. Leave the bag somewhere warm and dry for a few days. The silica gel packets or rice can help draw out the water from inside the watch.
  • Step 4 Direct a fan at the watch or use a hair dryer on the lowest heat setting to blow air on the watch. Alternatively, if you can safely leave the watch on top of a low heat source such as a floor vent or radiator, this can help evaporate the water from inside the watch.
  • Step 5 Obtain the appropriate watch repair supplies. If you need to purchase tools, look for these at a watch repair shop or at a jewelry store. You can also find watch repair tools online. You may need small, fine-tipped screwdrivers and watch openers and closers.
  • Step 6 Take off the back of the watch, as if you were changing the battery. Use care not to scratch or damage any of the mechanisms such as the coil or stem. Let the watch dry thoroughly in the open air until there is no trace of moisture. Reassemble the watch once it is dry and press the seal firmly back into place. If the seal does not fit tightly, you may need to replace it
  • jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); });

    I bought my relic watch last year around christmas time it claims on the back of my watch it is water resistant up to 165 meters i haven't even gone close to that depth for the past 3 months or so my...

    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.

    WHEN EVER IT GET HUMID MY MOVADO HAS WATER BUBBLES INSIDE THE CRYSTAL. IT TAKES DAYS FOR THE WATER BUBBLES TO CLEAR?

    mcdevito75 here, This is condensation, the difference in air temperature inside and outside your Movado watch, no watch is air proof, Humid means water in the air, the higher the humidity the more water is in the air. As the humid air enters your Movado it cools thus leaveing water behind, very much like boiling water, we see the steam, but put a cover over it and we see water, the hot air hitting the cover cools and turns back to water. However in your Movado this is too much and over time your watch will become water logged and be no good, Best Bet, look for a small watch repair shop in your area and have them re-seal the crystal and back cover of your Movado watch, also chek if your watch is still under warrantee, if so the re-seal should be free.
