I have changed batteries on watches before but none were bulova. I opened the back which you have to do to change battery find what battery you need and order online. I have been able to find at stores year ago but most watches now days people don't change batteries they buy new watches. It is a little harder to find batteries in stores.
When you find the type battery google to get the place to buy it.

It's actually a lot easier than that video shows. You're trying to represent a watch that is a PDA! To change the battery in your watch, you need to purchase a watch kit on eBay for about $15-$25, purchase the correct battery, watch a realistic video of changing a battery on Youtube, and then you will never need to pay more than the cost of a battery (a few dollars) to change your watch battery ever again! Sending it to Fossil takes time and money and you can do it at home with basic skills!

did you change the battery yourself ? You might have to resett he watch to have it started up . You only need to wind automatic watches. So no you do not have to wind your watch. It could be a bad movement

mcdevito75 here, Your Fossil watch should work with the battery change, of course it will need to be re-set. You"ll have to double check the battery install, make sure the battery contacts are clean, use a piece of paper towel and carefully clean the battery contacts. Hopefully your new battery is not dead. Another thing to check for, is that the buttons contacts are lined up with the quartz movement. While you double check your battery install, carefully press 1 button at a time, and make sure each button is making contact with the quartz mechanism, many times during a battery change to quartz movement may move just slightly but enough to keep the buttons from contacting the movement, this will keep the watch from working. Hopefully 1 or all of these is the answer for your Fossil watch.

If ANY watch is rated as water-resistant, then that guarantee of water-resistance is void once the back has been removed for a battery change. You will need to take the watch to an Oakley approved dealer for the battery change, or to any reputable jewellers/watchmakers/watch repair shop that will test the watch for you after the battery change. Testing is done 'dry' so there's no danger of water entering the watch.

mcdevito75 here, You:d need a couple of watch tools to change the battery, the cost of these tools and the cost of a watch repair shop to change the battery for you are similar. Look for a small watch repair shop in your area to save on the cost of replaceing the battery.

Yep, here it is....SR920W

Either bad battery or wrong battery.

Change the battery. This happened with mine along with the battery needing charging more frequently. In my opinion, Casio's assertions that you won't need to change the battery is pretty much of a joke. My jewler concurred.

After changing the battery I can now press the light switch button and the watch works normally.
