Chrystal front glass, a common item from any decent material house.

Nickel surround. That's called bezel, your only chance is to buy a very big lot of similar watches hoping in the small chance that one will fit. Otherwise, one can be made on a lathe, just be aware the work involved including plating will exceed 10 times or more the material value of this watch.

Also FYI, the introduction section of this forum is meant to introduce oneself even before asking questions.
