Does your Zodiac experience slipping cannon pinion malfunction (second hand moving but minute and hour hands still stationary)? Definitely it requires a service.
If you are able to replace the fourth wheel with pinion (part 200/1) but not sure how to properly repair it, buy this service. I'll inspect it, tighten and properly lubricate. You will receive the part, overhauled to the specification and ready to be installed on place.
If the pinion is not repairable, I have a NOS part in stock (available if full watch service ordered).
Feel free to contact me if you prefer to have your Zodiac overhauled completely.
