Jaeger-LeCoultre

My Master Date was factory serviced last January, and the one year warranty runs in a couple of weeks.  The watch is running slow, about -12/day.  I'm trying to decide whether to send the watch back to Dallas for what would hopefully be a warranty covered regulation/repair, or let my local guy take a look at it.  I'm hesitant to send it back to JLC if only because of the potential turn around time.  If the watch only needs to be regulated, my guy will do it while I wait.  This is my first JLC (I'm loving it), so am I correct in my assumption that regulation of the movement is a fairly straight forward proposition, such that a good watch maker can handle the task?  Your thoughts are appreciated. 

Of course they are some talented watchmakers everywhere, but it is always better to get the brand to handle your services, otherwise you might brake your watch relation with the manufacturer.  However tempting it can be, JLC service center would be more appropriate for you.

If your watch was services recently (12 months is recent even if depending on how you use it is a long time), I would suggest you contact your service center and get it looked at (time tested) to have it running as it should. 

Your best approach for it, (in your case) is to time your watch every day, set the time, and check again 24 hours later to report its gain or loss of time (possibly take a note of you've done every day (this to check what is influencing its gain or loss).  When you're past this 7 to 10 days, then send the watch with your report, this will help the service center to set the watch with more personal precision.

Good luck.
