I have a 25 year old Myota 4800-01A analog/digital watch. Recently, I had the battery changed. I don't think they used the correct battery...it stopped working w/in 2 weeks. What is the correct batery? Or, how can I determine the correct battery?

The same as the one that is inside it. There is no information online of this watch you have and its battery. They are a bargain brand sold on eBay and Amazon.
Changing Watch Batteries
Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!
Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!
The internet search using Google turned up the following discussion, particularly about the use of two batteries.
Unsure of how to resolve the problem, but it may be at the root when a battery is dead or newly replaced.
when a watch has analog hands and has digital portion, 9 times out of 10 it will have 2 batteries inside. A lithium battery and a normal battery. It is possible one died before the other. Usually the lithium (digital portion) lasts longer. Have the battery changed.
On average, I've found that analog wristwatches that use a silver oxide (or alkaline) battery last about a year after a fresh battery has been installed. Digital watches, because they have no moving parts, will typically last longer on a set of batteries if you're not using the alarm or backlight function. Watches that use lithium batteries generally last two years or more between battery changes.
Based on your model watch, I would guess that your battery has run down too far to power the movement. A fresh battery will probably fix your watch. Hint: in the future, if you aren't going to wear your watch for a while, pull the stem out into the "set" position. That will stop the movement and extend the life of your battery. When you want to wear the watch, simply set the time (and date, if you have a date window) and push the stem back in.
If you have a Fossil FS4337 Chronograph, shaking the watch shouldn't be doing anything other than exercising your muscles; the movement is a battery-driven quartz movement whose movement is controlled only by whether the stem has been pulled out (stopping the movement and saving power) or whether the battery still has enough power to activate the stepping motors that move the watch hands. Based on the symptoms that you've described, I would suggest that it's probably time to change your watch battery.
Often, when a watch battery is running low but isn't completely dead, pulling the stem into time-setting mode will stop the movement and permit the battery to "rest," giving it (briefly) a bit more reserve amperage to put out when you push the stem back in. That's how you can sometimes get a quartz watch to run for a few minutes after the battery appears to be dead. That may also be why your watch has started running again after you've set the time and date.
Fossil analog quartz watches tend to use silver oxide (usually #377 or #379) batteries instead of longer-lasting lithium batteries. In ordinary use, I would expect a silver oxide battery to provide between 1 and 2 years of service before it needs to be replaced. I can't remember if Fossil chronographs (which also use quartz movements) use a silver oxide or lithium battery. Lithium batteries often provide an additional year or two of service in analog watches, compared to silver oxide cells; digital watches using them supposedly may last as long as 10 years with a lithium battery, assuming you don't use the backlight or audible alarm functions. Note, however, that these batteries are different sizes and different voltages, so you can't substitute one for the other.
Finally, none of this advice applies if you have a Fossil watch with a true mechanical movement in it. In that case, gently shaking the watch may spin the winding rotor enough to start the watch back up again. However, an even faster way of winding those watches is to use the winding / time set crown to wind the mainspring directly instead of relying on the geared-down action of the winding rotor. Automatic watches can bind up if they are not used for a period of time; the lubricating oil used in some of the pivots can harden--or at least provide enough resistance that the movement may require more initial force to start running than to continue running. That behavior usually indicates that it's time to have the mechanical movement cleaned and re-lubricated.
There are two batteries in the watch. One for the digital watch and the other for the analog watch. The battery for the analog side probably needs changing but when the back is opened, you might as well change both batteries.
Quite often the battery can be the cause. But note that on some ana/digi watches there will be two batteries. The battery for the analog is usually buried quite deep in the watch and may be best for an expert to replace this. That expert will be able to test the battery first. If the battery is still good then I would suspect that the movement is faulty and may need replacing (although sometimes a bit of de-greaser expertly administered can solve the issue). Good luck.
this happens a lot the watch you have has to separate batteries both batteries were probably old. they tried replacing both but the movement on the analog part is probably corroded or rusty.
As it turned out these Mossimo ANA/DIGI watches use two different batteries, one for the digital part (big) and other for the analog mechanism (small).
Have the watch serviced to change the second battery and VOILA!!!!
