In the 19th century, the Swiss were not the pre-eminent watchmakers they later became. They made many imitation American watches, and they made many watches that claimed the provenance of famous British watchmakers. One such watchmaker was M.I. Tobias. There probably are 20 M.J. Tobias watches (or more) for every genuine M.I. Tobias. Some may have been retailed by Tobias' successors. Others likely were 19 Century equivalents of fake Rolexes, etcs.
The movement in your watch appears to be rather ordinary and typical Swiss cylinder mid-19th century movement, but there is nothing wrong with that, of course.
