Quits running and then starts back

1. Check the battery: Before attempting to set up your watch, make sure that the battery has not run down. If the battery is dead, you will need to have it replaced by a professional watchmaker or authorized Breitling service center.
2. Wind the watch: If the battery is not dead, you may need to wind the watch to get it started. Most Breitling watches have a self-winding mechanism, but if it has not been worn for a long time, it may need to be manually wound.
3. Set the time: Once the watch is running, you can set the time by pulling out the crown (the knob on the side of the watch) and turning it until the hands are set to the correct time. Push the crown back in when the time is set.
4. Set the date: If your watch has a date function, you can set the date by pulling the crown out to the second position and turning it until the date changes. Push the crown back in when the date is set.
5. Synchronize the time: If your watch has a chronograph function (stopwatch), you may need to synchronize the time to ensure that it is accurate. You can do this by starting the chronograph and waiting for it to complete a full revolution.

As your watch has 3 buttons I am assuming that it has the main dial and 2 sub dials maybee to show the date. The centre button should pull out (DO IT GENTLY) and either will stop or click ,you should then rotate it to set the time, when done push it back in to start the watch running.
The 2 outer buttons probably work by pushing them in a click at a time to set there respective dials.

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.

Don't know, don't know and don't know. You have to give us more information! The watch is warrantied by the manufacturer not Macys. See if they sell the watch in the UK

If you don't already know what size battery you need, you can find this information on the back plate of your watch. Once you have your replacement battery, you will need to open the back of the watch to gain access to the battery compartment. Depending on the watch, the back plate will either screw off or be attached by a few small screws. If attached with screws, you will need a set of precision screwdrivers such as a jewelry or eyeglass kit.

Inside the battery compartment, you will see the battery is held down by a clip. Carefully remove the clip and eject the battery. Insert the new battery and replace the clip. If the battery clamp indicates you should do so, quickly press the reset button twice. Then reattach the back of the watch. If the watch display remains off after replacing the battery, press all buttons at the same time to reset the display.

mcdevito75 here, I would imagine your Rolex is an automatic, not all Rolexes are. After 2 days not running at all your Rolex needs a very good start not just putting it on and that"s it. Sorry to say!, I would ask you to do this, With your watch close to your ear I would like you to wind the watch, listen closely, if you haer a clicking or a drag sound you know you have to give about 20 winds to your watch before you put it on, after the 20 winds the automatic takes over. If the stem just spins and no sound, Click or drag, then your rolex is fully automatic, after you put it on you"ll have to ttwist your wrist back and forth to get the automatic moveing to wind your watch somewhat. Twist your wrist back and forth maybe 20--30 times, this way your watch has an initial wind and as you wear it the winding continues with the motion of your wrist, after it"s wound pretty good if it stops and goes, have the watch serviced.

bad movement, get a refund or replace the watch

take and have it cleaned and oiled

This could be that the battery is slow. Newer swiss watches have a indicator in the movement of the watch that makes the sweep second hand skip every few seconds to indicate that the battery is slow. On regular japan made watches the watch just simply starts slowing down. Your watch could be new but the battery in it could have a long shelf life.

There is nothing wrong with your watch. Probably it's the one measuring heart rate and pulse (heart beats per second).
Use your users manual to set the watch.
By the way: Timex is one of the worst watch producers.
