I bought my first “real” watch a few months ago and I love it, however it has lost a lot of time over the past month and I’m concerned it could be defective. I’m pretty new to watched so I don’t know if this is common/normal/acceptable, but my GMT has lost 4 minutes of time since I set the time over 30 days ago using time.gov as a baseline. During those 30 days it has never stopped and I manually wind it just about every night around the same time. Is this acceptable or should I send it back to Seiko for a new one? Thanks!

Thanks everyone for the helpful advice. So basically this is normal and I’ll need to check my watch against time.gov every few weeks to make sure it’s not wildly fast or slow (like it is now at 4 minutes slow) and reset the time as needed?
