I am not an expert in these Series 100 watches, but I would be very surprised if a screw-down crown could be retrofitted to the current case. I am guessing that what you would really be doing would be switching out (replacing) the case. I'm not sure how replacing the case would affect the value; my guess, is that this would not have a significant impact on the value, up or down.
So enjoy it as is, or customize it, as you see fit!!
