·Thank you so much everyone for your feedback.
So what I have understood is, serial number can be in:
1. Case back
2. Inside case back
3. lugs
4. Movement
Referring to your 2.: You won't find the movement serial number inside the caseback.
Apart from very early watches, what's stamped or lasered inside the caseback, is the reference number of the watch, which specifies which kind of watch or model it is, but that's not the movement serial number.
