<human>: Can you provide a brief overview of the text?

Hello everyone, this is one of my first few posts here on Reddit, mostly a lurker but would like to become part of this awesome community, so please excuse me if this isn't the right place to ask this.

My girlfriend of five years is turning the big 21 in almost two weeks. Due to our busy schedules with school we aren't allowed as much time as we would like to bring in enough income to do a lot of fun things or even buy each other something nice for our birthdays. We usually don't do much other than just hang out which is fine, but I really want to make her feel special because the past year and a half of school has put a tremendous amount of stress on her. She's going to school to become a nurse and she holds her GPA at 4.0.

I've been saving up money for a while to get her a nice watch because she has wanted one for quite some time now. This is where I have encountered my problem.

I know the kinds she likes, but in previous attempts to buy her gifts at the beginning of our relationship I bought her a gift that she told me she loved and used it for quite some time only to find out later that she didn't really like it while being to embarrassed to tell me and hurt my feelings.

I know if I spend $200-$300 I have on a watch I want her to LOVE it, but I'm not very good with girls fashion and what not as I'm pretty plain when it comes to fashion.

I've narrowed down my choices to these following watches in no particular order:

She's shown me watches similar to these, I did my best to try and find ones she's shown me previously.

If you're still here with me reading this post, thank you sooooooo much! I can answer any questions you might need to know about her and what she likes. I will be posting a picture of us soon so you can get a better idea of her.

If any of you out here on Reddit could be so kind to take time out of your busy day and help me surprise my wonderful, beautiful girlfriend who very much deserves something nice for herself it would be much appreciated!
<bot>: I'm afraid of buying an expensive (for me) watch for my girlfriends 21st birthday that she might not fully like and would be too embarrassed to tell me she doesnt want it while still wearing it anyway.
