rather than post another thread I thought I'd post in this one. My DSN 177 started running lightning fast today. I'm talking 5 minutes an HOUR. The Zigmeister, this watch was previously serviced by you when it belonged to slai and it has been running like a top for over a month since he sold it to me. I didn't wear it all weekend, wound it up this morning and headed to work, halfway through the day I noticed how fast it was.
Since it's been serviced, I guess the hairspring maybe? I didn't drop it or bang it on anything that I remember, not sure how I could have done that?
