Vincente was the maker and won an award in 1855, which means that your clock can not be older than that year but is most likely closer to have been manufactured in the 1880s, as others have stated.Evidently it was made in 1855 by Vincenti Medaille D'argent.
You're welcome. The manufacturer doesn't change the value particularly, it's just useful to be able to make a definite attribution. I'd still say about $150 US, the condition really does hold it back.
