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.

HELLO Marijane,

To get the BACK... back on you will likely need a press.

The back opener for snap back watches

(my opinion) can be seen on eBay at

A jewelers loupe ( about 10x power) will help you fond the precise spot to leverage.

Your GOAL is to open the case leaving the LEAST amount of
tool marks. Every time the case is touched,,, it leaves a mark.

THE reason I got into doing watches myself...
huge scratches left by a "PROFESSIONAL".

I suspect you should also (very likely) need a set of jewelers screwdrivers...

All abundantly available on eBay.

Happy hunting!

The Proper way is with a "watch case wrench". They can be purchased for a few dollars on Amazon and E-bay. In most cases unless you are changing many watch batteries the best option is to call around to local jewelers and pawn shops and ask how much to replace a watch battery. In my town it ranges from $30 to as little as $5.99 battery included.

some watches have a notch that comes out where you can get a knife, or exacto blade underneath to pop it open. if not, there may be multiple intends along the ridge that would require a special tool to twist open. any jewler could change the battery for you. also, batteries plus stores can change the battery out at a reasonable price.

You need to open watch case back using appropriate tools. There are two batteries in this model - one for each watch movement. Unscrew/un-clip battery contact. Memorize polarity (+ and -). Take the battery to your nearest watch battery shop or watch repair shop and buy the same one. Fit new battery back in watch (remember polarity!). Fit back contact as it was. Close the watch case back. Set the time. Done.

BASIC WATCH BATTERY CHANGE
Get a replacement battery for your watch. Some watches have the battery information stamped on the back plate. If yours doesn't, you'll have to wait until you've removed the old battery to see what kind of replacement watch battery you'll need.
Lay your watch face down on a non-scratching, non-skid surface. It may help to clamp the watch to the surface.
Remove the back from the watch. You might be able to pry it off with your fingernail, but you'll probably need a stiff, thin tool like a knife or screwdriver. You can also buy watch repair kits, which have the perfect tools for the job. Check the watch back for a small notch to insert your tool, but not all watches have these.
Remove the battery from the watch once the back is off. You might need to tip the watch over to let the battery fall out.
Insert the new watch battery into the proper space, first double-checking its size against the old battery to make sure it will fit. Press lightly into place.
Replace the back on your watch. Make sure you press firmly to get the back seated snugly.

If this doesnt work, then take to a local jeweler/watchmaker who is equipped with the right tools to assist you.

Best regards.

Most Skagen watches have a snap-in, snap-out back. You will need a tool to open the back such as a slotted jeweler's screwdriver or knife blade to pry it open. Be careful opening the back as the battery may pop out. Examine and make note of which side of the battery is up. Get the number off the battery, or take the battery with you to Wal-Mart, Radio Shack or anywere else they sell batteries. Buy a replacement, install it, and try to reinstall the back. You may even consider taking the watch with you to the above retailers...some of them are willing and able to change the battery for you.

good morning ! if your watch is waterfroop design that`s have a tread so if you want to open the case back you need a wrench or opener, but if your watch is snop in design you need a knife to open the case back,and change the battery,thank you,
