I don't normally bash too hard on fashion watch brands for women, but I've seen some bad quality issues with MK.
I think VSA and Citizen are solid choices. Citizen is probably more conservative while Victorinox is sufficiently conservative yet readable. It won't be on the extreme end of conservative for a ladies' watch though.
I'd also throw Bulova into the mix. They have good options right at the $100 price point. Seiko is fine as well but I haven't been as impressed by Seiko lately as I have with Bulova.
