Great, thanks! It is somewhat odd that the tiny 221 movement has 15 jewels. I did look at one of mine last night and, as mentioned, no jewel count on the movement. Checked my copies of the service manuals and jewel counts weren't given there, either. I think the 219 movement is the only Accutron movement that was truly "simplified" to reduce costs. IIRC, they sold for as little as $75 at the end of the Accutron run. I have a few and, properly serviced and set up, they run well and keep good time. The Accuquartz 221 movement has turned into one of my favorites. I have 6 of those and one is unbelievably accurate - lost only 3-4 seconds in almost 5 months!
