Submariner Willed to a Watch Killer

[Ted Hoffman]

I am new to the forum and a longtime Rolex owner.
In making my will a very close and long time friend will receive my Submariner at my demise.
Now I find out that she cannot wear watches because of her make up she says that the watches will die after a couple days. I want her to be able to wear the watch because she is a very good friend .
My questions are 1. What condition does a person have that they cannot wear watches? 2. Is there anything that I can have done to the watch that keep her from killing the watch.
I did neglect to tell you that the watch is a Stainless Steel Submariner 1991 vintage.
Thanks

Teddy
