Okay everyone I need help. As most of you know I was given my stepdad's watch over the Thanksgiving holiday. I have replaced the batteries and it is now up and running. However, it loses around 7-9 minutes every 1-2 days. The day/date complication works, but ends up displaying the wrong day/date. I'm thinking this is due to so much loss in time. I have plans to take it to our local watch store but wanted to get everyone's opinion on what could be causing this? I'm thinking maybe a bad moment or the crystal. Thank you in advance for everyone's input.
