end link question

[SB10042008]

I've worn my Exp II for about 7 years, and I recently noticed that the the end link is becoming loose and there's a small gap between the end link and the case. The watch is due for a service anyways, but what I'd like to know is

1) Do I need a new bracelet?
2) Until I get this fixed, is it safe to wear the watch?

Thanks.
