So I recently purcahsed a Sinn 140 A secondhand from a user here on the forums. Transaction went well and I think both parties were satisfied. Now my issue... I've only had this watch for ~ 45 days and today while wearing it at the office I noticed the Minute hand wasn't moving forward even though the second had was continually working. I also noticed the that Second hand for the center Chrono Hand will stop after making 1 round and getting 'stuck' at the 12 o'clock position. Reset seems to work, but it gets stuck. The 140 is almost acting like it's power reserve is Zero, however I can manually wind the movement a few rotations from the crown and I can also hear/feel the weighted rotor spinning around.
It's like something is 'stuck' and preventing the watches movement from fully engaging.
I LOVE the looks of this watch but I'm very disappointed to say the least. I don't have the warranty card with me so I'm not sure the actual date on it... and since I'm not the original owner I'm not sure that Sinn will warranty the fix anyway. I was told that RGM is an Authorized repairer but I've never used them. I have in the past sent a watch back f/the US to Germany for Sinn to repair it. I just hate to have to go that route after spending several $K on this watch and only getting 45 days of use out of it before needing repair work. It still looks new. Don't think it's ever been dropped or banged on anything. The Capsule is still a very pale blue so that's in good shape as well.
Thoughts on what I should do? Should I reach out to Sinn and just ship the watch to them for repair or would RGM be a better option since I live in the US?
Is it possible that I just need to wind the movement more since today was the first time I've worn this watch in ~ 4 days so this morning when I put it on it was dead. I wound the crown a few times, set the date/time and proceeded w/my day.
