I picked up a new Marine Original directly from Stowa about three weeks ago and noticed that it's been running fast. However, it's very irregular. I monitored it and noticed that there are many hours at a time it runs fine, and then suddenly spikes to running several dozen seconds fast for a short period, then returns to normal. The net affect I'm seeing is it's overall increasing time, but even across a span of many hours it runs with no variance.
I popped it on a timing machine and caught a sample of the erratic behavior I'm speaking of and wanted to get an opinion. It's a new watch - is there anything weird at play with the hairspring? My other watches do not have this erratic timing.
