re: OT Watch Enthusiasts: Do you use a watch winder?

My Rolex dealer recommend a winder when you are not wearing an automatic watch for greater than two weeks. He said that if a watch sits inactive for too long, the oils and grease that lubricate the inner gears could pool to the bottom of the watch. He also recommends that you get your watch tuned-up every 5-6 years.

As far as accuracy... My mechanical watches are a lot less accurate than a good quartz watch like Citizen or Seiko. Sometimes my mechanical watches could be +/- 5 minutes per month, while my Citizen/Seiko would only be a few seconds off compared to atomic time each month.
