I recently bought the Theorema OMAN GM-108-3. I like the watch very much but it's running too fast. I know it says in the instruction booklet that a mechanical watch won't be as precise as a quartz watch - but my Theorema is fast by almost 10 seconds per minute (after one minute passes on the OMAN only 50 seconds passes on my stopwatch), meaning every 6 minutes my watch is running one minute too fast. And quite frankly that's not good enough. I have to adjust the time every 6-10 minutes for my OMAN to keep time. I believe there's a malfunction in my timepiece and I would like to send it in for repair.
