My battery is only lasting about 12 to 14 hours. I have taken it in to the apple store and they said to turn the watch off and reboot once per week. They have also diagnosed the battery quality and it is showing good. I have also turned off the background refresh but it is still about the same. What could be the issue?

Battery life between charges depends how you are using the watch. The big consumers are usually apps which do a lot of data traffic or keep the screen alive for long periods, and standalone cellular operation with a lot of calls. Apple cites a battery life around 18 hours with their standard test conditions, but you may get anything between about half of that with heavier than normal use, or several days if your usage is particularly easy.
