Hello I have a movado 800 series sub 200 and

Is it a Chronograph. Sounds like it is stuck on Timing.

Did they put the correct battery in?

I was told my a jeweler that Movado condiders that. Design defect and they don't produce or offer that rubber insert for sale.

you do not need to return, as this is re-settable. Pull out crown to the first position (date setting) and then toggle with upper push button. If upper button do not do the job, try the bottom one. When you reach 12, then push the crown back in. Start the chrono, stop it and check if it returns to 12.

Try this site. I have the same watch and the instructions are avaialable from the Movado support site: http://service.movadogroup.com/movado/

Try pulling the crown out and using the reset button to move hands beside the sweep arm. If this doesn't work then you may need to take it to a repair shop that can reset or AC the watch. With a movement as fine as Movado I wouldn't attempt this yourself. If you make a mistake the repair could cost more than the watch. Be sure that you have the watch resealed so it maintains its water resistance.

Yes, the Movado is a self winder, and it was designed for the sports active wearer, of which the motion of the wearer's arm provides the power to keep the watch wound. Apparently you are not active enough for the watch to be fully wound, so when you take it off, it will use up all of the stored energy in the spring and stop. many self winders will only store enough energy for 8-12 hours of use and will require constant wearing. You could try wearing it to sleep and see if this is enough to keep it wound.

If you feel that this is not the case for your watch, then you may want to have it looked at by a watch maker

I wouldnt try to return it. I would go back and inform the store of the problem you have and they have no choice but to either fix it, show you how to solve the problem, exchange it, or at the least, return it but please give them a chance to fix the issue.
Best wishes,

mcdevito75 here, Movado a FINE watch, BEST BET, look for a small watch repair shop in your area to change the battery, Movado watches have a very good over all value and any damage can lessen that value, not to mention the jewelers screwdriver you"ll need to change that battery.

Assuming it's not a quartz watch try winding it fully - about 40 turns of the crown. If you wear it daily it won't need further winding unless you skip a day or you're not very active. The watch is typically wound by the movement of your arm/wrist. Manual winding will compensate for the lack of movement.

The chronograph can be reset by pulling out the crown to the first or second position and pressing the start button or top button. This will begin to move the sweep arm and you can stop it on the 12:00 or 0 position. Make sure that when you have the battery changed they do this for you.
