Best way to open a stuck back shield - Beverly Hills Polo Club 23909TT Wrist Watch

Hi,

please view the back of the watch and look for screw or plastic latch that you can use to open the back and access your watches battery. You can search amazon or bestbuy for a replacement battery and then order it. But if you find it hard to open the back of the watch, you can visit a local watch store to help you with that and they might have a replacement battery for you as well.

Thank you.

Best to take it to a jeweller as battery replacement if not knowing how can damage the movement. Otherwise a screw back has little notches on the side of the back and a press back is smooth. You will need a back opening knife to open.

Yes, the battery for this watch can be replaced. Timex estimates that the battery should last 2-3 years, but that assumes an "average" use of the Indiglo backlight. If you never use the backlight or audible alarms, your batteries would have lasted longer; heavy use of both would have run the battery down more quickly.
If you want to replace the watch battery yourself, you'll need a very fine philips or flathead screwdriver, the new battery, and a bit of patience. It would also be helpful to have a pair of tweezers, but that's not absolutely necessary. If you carefully look on the back of your watch, Timex usually lists the battery type so that you can buy a replacement battery without first opening the watch. If you can't figure out what the numbers mean, take it to a jewelry counter at Target or Walmart, and they should be able to help you decipher it. I don't know which battery this specific watch takes, but many Timex watches use a #1620 or #2016 3v battery. Look for a number like that on your watch back.
To open up the back of the watch, open the strap so that you have good access to the back. If you have a steel band, you might need to slip out one of the adjustment pins to separate the band into halves. Yes, you might be able to take the back off without this step, but it makes it a lot easier.
Place the watch face down onto a soft surface. I like to use a dark towel, so that if I drop one one of the tiny screws you'll be dealing with in a minute, they won't bounce and you can easily find them again.
Use your screwdriver to loose the back of the watch, one screw at a time. I find it very helpful to loosen a screw, then use the tweezers to pick it up out of the hole. These guys are tough to grab with your fingers! Put the screw in a safe place, then carefully remove the back of the watch. A little black neoprene gasket may be stuck to the back or be floating around--don't lose that!
You should be able to see where the battery is kept. On most Timex watches, there's a metal shield covering the watch and completing the power circuit. Using your screwdriver, gently pry the tabs of this shield away from the watch movement, one tab at a time. Try very hard not to snap off any of the little plastic anchors. On a Casio watch I recently serviced, I had to remove the movement from the watch to get at these little tabs; I don't remember ever having to do that with a Timex.
Once the shield is loose or removed, the battery should slide right out. Replace the battery, and gently snap down the metal shield. Turn the watch over to check whether it's working again. If it's not, you may have to push a little "reset" pin on the watch movement to clear the registries. The back of the metal shield usually has instructions on where that little pin is located. If the watch is already working, you won't need to do this.
Closing up the watch is the reverse of what you did to get it open. Make sure the neoprene gasket is back in place--that's what's keeping sweat and water out of the watch--and carefully set the cover back in place. Tighten the screws in an "X" pattern--i.e., top left, then bottom right, then bottom left, then top right. I get all the screws loosely screwed in before tightening them down in earnest. This watch has a plastic case, so you want to tighten the screws snugly, but not over-tighten them so that they strip out the screw hole.

The "pin" you're describing sounds like the pin-set lever, which would be used to set the time. Pushing in the pin while turning the winding crown will move the hands forwards or backwards, depending on the direction in which you're turning the crown.
If you are trying to see the rear of the watch movement--i.e., where the balance wheel is ticking--and you can't see anything after removing or opening the back cover, you probably have a watch case with two back covers. This is not uncommon--the first cover might have engraving or a photo inside it; the second cover would serve as a dust shield. While the rear cover may screw off or be hinged, the inner cover is almost always hinged. Look for a tiny divot or imperfection in the dust cover where it does not seem to cleanly meet the rest of the case. Insert a case opening knife (or just a dull pocket knife blade) into that opening and *gently* twist. Do not get too aggressive here or you could deeply scratch the watch case and/or skitter across the face of the watch movement, significantly reducing the value of your pocket watch.
The dust cover should pop open with only a small amount of pressure. Swing it back, and admire the view of your pocket watch movement.
If none of this matches what you're seeing on your watch, follow up with any identifying language about the type of watch case that you have. Typically, the manufacturer will stamp some info inside the outer-most back cover of the watch. Note that the case maker is probably not Rockford; movements and cases were often sold separately and mated together at a jewelry store. That way, people could put a good movement in a cheap case, or a cheap movement in an expensive gold case.

mcdevito75 here, Once the battery leaks it destroys the quartz mechanism. Even if you find a replacement quartz, you"d need special Jewelers tools to remove and replace the quartz, even with that you could destroy the new quartz if you can find one. Best Bet, see a small watch repair shop in your area for a quartz replacement approx. $75.00

mcdevito75 Here, That muct be part of the Mechanism itself behind the crown, Best Bet, look for a small watch repair shop in your area to fix the watch, as the watch could be ruined by trying to get a stuck crown and stem back in. Or you can visit the repair service directory here at fixya, bottom of the page click on repair serice directory then watches.

Most watch backs either screw off with a special case opener that every wachmaker uses or pried off with a knife like case opener or sometimes a knife. Take this to your local watchmaker for battery replacement. Batteries are readily available but are a bit tricky to install properly and are best installed by a qualified watchmaker.

Yes, the big, round thing in the middle is the battery. To get it out you need to unclip or unscrew the contact covering it. When the contact is off you will see the battery number written on battery - buy exactly the same one and replace. After replacement you will need to set the watch manually.

You are right, this type of watch can be opened by lifting crystal and extruding the stem. As for lifting the crystal you need a specialized tool, there is no other way then to go and find your nearest watchmakers shop. If you will try to lift the crystal using knife or any other unspecified tool, you will damage the crystal. Even if you will be lucky enough to get it out without any damage, you will not be able to fit it back, because the watch crystal setting tool reduces the crystal diameter for easy fitting.
Best solution for you is to see the watchmaker and ask for help.
