The product is a very rare pocket watch featuring a Zodiac dial and a heavy brass case. It is a unique and special timepiece that stands out for its design and materials used. Swiss made for the Asian market in the 1800’s, working keeping perfect time. As you can see the dial is very interesting Roman numerals for day and night. I have never opened it but running so nice I did not want to disturb. I will try to answer any questions you may have.
