I am trying to reset my watch for a workout at at won't reset.

Very Nice watch for the price point. The watch functions are quite simple, and that is what I wanted, as I plan on using this for workout purposes.

Please visit my tips and tricks page for reasons why you are not getting a signal. if it takes that long, the number 1 thing to look at is conductivity - so you are either not getting the strap wet enough and takes enough sweat to build up to get a god signal, or it is out of position and takes till you get the strap really wet to make the signal strong enough.

Another thing is turn the watch on, away from other input sources so the watch will key on you, if it is receiving signals from others at the start it will have a hard time knowing which signal to use.

Same issue, no need to sync my watch

NO, don't open the back cover you will break the water seal.

Reset the wrist unit. Resetting clears the date and time settings.
Press all buttons except the Light button at the same time until the display is filled with digits. Press OK.

If this does not work, have the batteries checked.

Yes, you definetely need battery replacement.
As the hart rate monitoring is most sophisticated part of the device, it has more IC (Integrated Circuits) than any other features.
More IC's means more power is needed, so, if the heart rate monitor is starting to malfunction, that's the very first sign of underpowered battery.
Find your nearest watch repair shop and ask for battery replacement.

Do not forget to rate, please.

Yeah...it took me awhile to figure this one out too.

You can't actually reset the Review function back to zero. Instead, you replace the data with your latest workout.

Here are the steps:
1) turn on heart rate monitor
2) setup HRM zone
3) start chronograph
4) do your workout
5) stop chronograph
6) review your results

Starting the chronograph is the key. This is the step I missed
