You can sync ur watch time here:

Then check ur watch daily, weekly etc, at a fixed time and see how far it goes off with the actual time in the link above.

Cheers

Alternatively, click on the time in ,say, your notebook: thence to internet time which allow synchronization to an internet time server
time.windows.com.
