Does not run. does this watch have a battery in it?

The 377 battery is located behind the CR2016 battery. You will have to completely remove the motherboard to change out this battery that runs the analog portion of the watch.

Does it come with a battery in it? I've had watches where there was a little clear plastic tab you had to pull to allow the battery to make contact and the watch to run. If not, then all I can suggest is to but another brand of watch. Here's their web site link. At the bottom of the page is the contact link...good luck.

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.

Automatic watches are spring driven and therefore do not have a battery.

Automatic watches thrive on being used and if you do not wear them sufficiently, they will run down and stop (or perhaps they run slowly before stopping).

Your watch should run for 38 hours before stopping.

This watch will most likely run on two batteries - one for the ana and one for the digi. Usually the digi will run out faster if you have an alarm or lamp on it. When you replace the battery always use top quality swiss or german made batteries. Use Renata, Rayovac or Varta as a preference.

If the watch is not running it's probably the battery. To set, pull the crown out and turn to adjust the time. Push the crown in to run the watch. If the watch is new the battery should be OK but take it back to the store if it doesn't run. If you bought it used take it to any watch shop for a battery replacement. Sears does it for about $8 or less.

Turns out (IN OUR OPINION)

That letting the watch run is far better than turning it off.

Due to battery draining over time, and Just fact that if its not running for an extended amount of time it may not restart.

If planing to leave it inactive for extended time have the battery removed if not just let it run.

Hope this tip helps.

Have had numerous customers come in and have battery changed in a watch that was working fine. stopped the watch and the watch would not restart. (Just our humble observation).....

It could be that the battery has a poor contact. Try cleaning the battery with surgical spirit and avoid handling its faces.(hold the edges).

Clean also the watch contacts.

A lot of times they hide a second battery for the analog display under the larger battery used to run the digital display. Also, the 2025 may not have a full charge.

That is way too fast for a Seiko Kinetic. There is no adjustment to slow it down. With time of course it might run slower as the gears get dirty. Maybe Seiko will replace the movement, worth asking
