It is a large watch, but if you're comfortable with the size and weight, then go for it. It looks lovely on your wrist.
For me wearing a men's watch goes beyond "chic.".I've worn larger watches since the 1990s. I needed a larger sized timepiece so I could time my medication. (I do own "normal" women's watches, but nothing under 28mm.) I have a six inch wrist and I went through as stage where I wore humungous watches. 45mm plus. I stopped doing it because I'm not that tall and it would freak people out . 41mm-42mm is the largest I wear now. Most of the time I sport a 38mm.
There's always been a very small number of women who've worn men's watches for various reasons. They like the size and quality. You have to be very confident when choosing to wear a men's watch. Even though it's been a trend for quite a long time, people are divided about it. A lot of men hate it. Perhaps it's because watches has long been a "men's thing" and they feel threatened?
In the end, you do what's beat for you. Since this is a Rolex, there's no problem trading, selling, etc. --should you change your mind!
