Really Bummed about my Malfunctioning Rolex

[stones]

Thought I would post this in case any of you have experienced a similar problem.

I purchased a YM new back in Feburary of 2011. I wear the watch almost daily (skipping only an occasional day on the weekends) and have never damaged or abused it in any way. This weekend I was wearing the piece and discovered that it had stopped. I attempted to manually wind the watch and it started again for a short period of time before stopping again.

Normally it is not really necessary for me to manually wind the watch based on my wear. I have noticed however that it does not seem to hold a full wind for the 36 hours as stated in some of the information I have read since I have owned it.

The YM is only 18 months old and now I am sending it for service. Have any of you had a similar problem? Really concerned as I shouldn't be having this type of problem.
