You are way off mark. I collect watches (including Rolex). I am what you call a Horologist. Anyone who tells you that you can identify a Rolex by how the second hand moves knows nothing about Rolex. You can get watches for $10 with nice smooth moving second hands. 1. Some 70's era real Rolex do use batteries. If the watch says Oysterquartz on the front then it is a battery powered watch. 2. You can only get the battery at a specialty watch shop. The battery type was common in the 70's but not today. 3. If the watch is 40 years old, then the battery has leaked inside by now.
Modern Rolexes have perpetual (automatic) movements, meaning the watch is powered by the movement of your wrist. When you move your wrist, the rotor winds the watch. Vintage caliber 3035 movement. If you wear your watch daily, the rotor should do a sufficient job of winding the movement.In the event you donât wear your automatic watch daily, itâs important that you manually wind your watch for it to keep accurate time. Winding your watch is an easy process.f your Rolex is still losing significant time after winding it, take it to an authorized Rolex service center. A watchmaker can tell you whatâs wrong with it and possibly save you major money by conducting the repair on-site before you ship it off to Rolex for hundreds (or thousands) of dollars.
