Welcome Matt. The Tag Heuer 'Monaco' has been in existence since 1969 and has been sold in numerous configurations and with 5 different movements since its inception. The closest i could find to your watch was the Monaco "LS" series but unfortunately your pic isn't really clear enough to pick out details. Usually though, TAG enters their model# on the case between the lugs which likely means you have to remove the bracelet to see it. Maybe someone else around here has a better idea.
