Oooh, the clock shop sounds really interesting!

I am not in a non-traditional job, but I work in a male dominated field in a male dominated industry. The biggest annoyance is feeling like people don't take me seriously because I am female. There are some sexist comments but they aren't a huge problem. On a day to day level, it's okay/not bothersome, but I get annoyed on a macro-level because I feel like my options are limited because of my gender.

It's really going to be environment specific, too. Some companies will welcome women in non-traditional roles and some corporate cultures will be hostile. If it doesn't work out for you at one place, you can move to another.
