Picked this VHP up in May preowend and was spot on to the second up until 2 weeks ago. Second hand started fluttering so I figured battery needed replacement. Took it back to place of purchase for replacement battery, free of charge, and picked it up yesterday. It's a full 41 seconds off today where it wasn't missing a beat before. Curious if anyone has run into the same problem and what it took to correct it? Any info is much appreciated! A bit crazy that my Helm with the NH35 movement has been more accurate the the VHP quartz for sure.
