I recently serviced this important family watch, a late 1950's Rolex Precision Reference 6466 Calibre 1210, for ClockSavant customer and fellow Instagrammer @pbhome. If you haven't already, you can visit the ClockSavant Instagram page and stay up-to-date with the latest posts and our over 5000 followers. This watch belonged to his late father. His father received it from an important government dignitary when it was new. The watch had significant wear and past watchmaker abuse over the years and was barely running when received. However, vintage Rolex's of this era are a bit like Rocky Balboa-- they fight like hell to run again. It's now running superbly once again after servicing, exceeding all my expectations. Highlights of this service included the past watchmaker installing a broken jewel retention spring (red circle in photo's); removal, to the extent possible, of some kind of glue/epoxy added to the inside of the case to address corrosion which in-fact promoted it; replace various wear parts; addressing past watchmaker abuse to the barrel bridge; and installation of a replacement case tube, crown, and stem. The watch was filthy and loaded with oil and grease. It's now ready again for future generations.
