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.
1 Donât try to sell a used Rolex if there is rubber to be found anywhere on the band or case. 2  Itâs fake. 3  Donât try to sell a Rolex watch if it has a skeleton dial (a dial that displays the moving parts of the watch). 4  Itâs fake.
