Hey Steve, I would think just about anything would work to glue in a pallet jewel 😯 BUT 😯 if you use shellac you can adjust by reheating it, I have heard that some use super glue, but if the jewel isn’t set right you would have a better chance of breaking the jewel trying to un-glue it and move it..then you waste time and money getting that too 🙄 . It is really cheap to get shellac, alcohol lamp and even a pallet warmer, maybe $20, to me this would be the right way, keeping your watch original and in the end easier and cheaper. Have fun!!!!William
