the watch movement deters which battery the watch needs it is very important you do not put a battery in that doesn't suit the watch as it can short out the circuit however you can get the correct size in a gold seal quality which should not leak, also the older the watch, the more demanding the watch becomes on the battery as the movement components start to experience wear and tear

mcdevito75 here, That dial is used mainly on Divers watches for Divers, by setting this dial, you can tell how much air time tanks that divers use have in them. It"s main purpose though is to hold the crystal asssembly to the watch case. A specialized manual can tell how to use this outer dial, it can be used as a measure of distance and time.
