Honestly speaking, there are many different ways to successfully do this and they all will work. Some people use UV cured cement, and it will work fine, however there are reasons I don't like it (and I should mention I've repaired watches since...well for decades). If you read comments on the internet, you are likely to see dire warnings about lens element alignment. Trust me, you can use your tongue to sense proper alignment. It is able to detect differences of less than the thickness of a cat hair.
