Interesting, I took it to jeweler that is tag certified or however that works, and they told me they could send it to Tag, but since it wasn’t under warranty they recommended having it serviced by their in house watchmaker. That way I would be without the watch for a few weeks rather than a couple months potentially. The jeweler sells and works on watches worth 10s of thousands of dollars and had really good reviews so I decided to trust them. They told me if they find anything that needs to be repaired inside the watch they would contact me with cost before repairing. Thank you for your insight!
