Sounds like a good thing to talk over with your artist during the consultation:
A pocket watch seems like a pretty neutral object: with gears and mechanical touches it could be interpreted potentially more "masculine", with flowers/hearts maybe more "feminine", but at the end of the day who cares: Let the artist know what you want, some ideas/guidelines, and let them do their magic.
No matter what happens there'll be people who love it, hate it, and everything in-between. The only opinion that matters is your own!
