Oil or Don’t Oil? A variation of this post appears in the “Clocks” section of the Message Board. Should this movement be oiled? If so, how is it done without making a huge mess? The movement is teeny. Last week I bought this clock. I’ve always admired the concept of the pendulum-driven movement, as it runs with much less gear and bearing contact force. Plus, I like to watch it work. The main vertical support plate has this on the front: Junghans ATO On the back is a serial number: 518959 The movement is marked on the front: Henry Coehler Co. Inc. No (0) Jewels Also: Unadjusted Made in Germany The clock is driven by: Horolovar Long Life Battery Size 8 or 9 From what I’ve found out so far I have decided not to oil this clock. I would only make a mess of it and I do not believe the mechanism requires it, as the operating forces are very small. Also, can anyone tell me what I’ve got?
