The Portugieser Yacht Club Moon & Tide is a watch that shows tide information. A subdial at "6 o'clock" indicates the expected times of the next high and low water. A reduction wheel train translates the regular rhythm of the hours into the constantly shifting time sequence of the tides.
On most coasts there are two high tides a day, always 12 hours and 24 minutes apart. The double moon phase display at "12 o'clock" is enhanced to show spring and neap tides, so it also shows the strength of the current tides. Spring tides bring particularly high water and occur at full moon and new moon.
The case is 18-carat 5N gold. The dial is blue, with gold-plated hands and 18-carat gold appliqués. The IWC-manufactured 82835 calibre has a Pellaton winding system and ceramic components.
