When I got the watch and for over a year, it lost a minute of time every day. It stopped working and about a month ago, I had the battery replaced. It was no longer losing a minute every day while it sat on my dresser. The first two times I wore it, it lost about 20 minutes in a couple of hours, but went back to keeping good time while sitting on my dresser. I wore it last on 5/11/24. It lost about half an hour while wearing it for 3 hours or so. I put it back on the dresser. When I looked at it that night before going to bed, it had lost about 4 hours. This morning I set it to correct time and it kept good time all  day on the dresser.
