Q&A for How to Change a Watch Battery

To open a screw-back watch, first assess the type of watch and its specific requirements. For older pocket watches, like those from the 1920s, grip the watch firmly and use a piece of firm rubber or rubberized fabric under the case back. Apply gentle pressure with your palm to turn and unscrew the case back. Exercise caution to avoid damaging the threads. For other watches, look for small cutouts around the outer edge of the case back. These are designed to accommodate a wrench. Use an adjustable wrench, such as a Jaxa wrench, to fit the bits into the cutouts. Once positioned correctly, turn the wrench anticlockwise to release the case back. Remember, opening a watch exposes it to dust and moisture, potentially compromising its integrity. Proceed with care to avoid damaging any gaskets, which may need replacement after being decompressed from years of use. If unsure, seek assistance from a professional watchmaker to avoid costly mistakes.

Usually, a very fine tip flat head screwdriver is what you need. You can get a set of fine Philips and flat drivers in what is often referred to as a "jeweler's" screwdriver set, usually for under $5.00 (US).

Make sure that you're properly lining up the dials on the watch before applying a lot of pressure with your fingers onto the back of the watch. You might need a special tool to apply more pressure if it's not properly snapping back on.

The battery could be not right one, or the battery holder is broken. Go to a watchmaker for further help.

It has to be removable. If it has screws, unscrew it. If it doesn't have screws, look on the side of the cover for a flap or a part that's like a flap, or an open space. Use a knife or something to pry it open. If you can't pry it open, then go to a watchmaker to open it. Now the pry open kind of watches are hard to put back, so be super careful.

Go to a watch store, and ask them to try to get it out for you. It might have rusted shut, so it might not work.

No. This battery is used to replace 280-205, 5003LC, BR2025, DL2025, ECR2025, and SB-T14 batteries.

If you have a jewelry shop near you, go there and ask for a watch battery. Be sure to tell them what the brand is so they know what to get for your watch.

Your watch can be affected by static electricity or electrical equipment, but not your body.

Yes.

Watch screws are anywhere between .30mm and 1.20mm. Take your watch to a professional so they can test different screws and determine what one you need.

As long as it's connected to your phone it should.

Usually there are marks on the outer edge that a case wrench will fit into to twist, and then you can remove it.

Most watches use batteries unless they are quartz watches that use solar power.

In this case, look for an indicator notch on the side of the back casing. And with a very fine flat head, you can gently pry the cover off to reveal the watch compartment.

This watch may be a front loader where the glass has to be removed in order to access the watch movement. Take this watch to an horologist for more advice.
