Port Royal Chrono, ca. 2003,
A gift for the 50th Birthday

After very carefully removing the 6 hands and the dial
There was this beautiful view of the Caliber 400Z from the dial side. I very checked the surface, glanced into every opening and even removed the largest (calendar mechanism) bridge visible. The third screw is still missing and must be lodged somewhere deep inside the movement. Now it was time to make a parts layout and look-up the authorized Zenith dealer in town.
