The Portugieser Yacht Club Moon & Tide Story

A complex interplay of gravitational and centrifugal forces between the earth, the moon and the sun causes the tides. On most of the earth's coasts, there are two high tides per day, always precisely 12 hours and 24 minutes apart. The Portugieser Yacht Club Moon & Tide indicates the expected times for the next high and low water on a subdial at "6 o'clock". This is achieved by a reduction wheel train which translates the regular rhythm of the hours into the constantly shifting time sequence of high and low water. The double moon phase display at "12 o'clock" has been enhanced to show spring and neap tides and therefore also informs about the strength of the current tides. Spring tides, which bring particularly high water, occur at full moon and new moon. The 18-carat 5N gold case, blue dial, gold-plated hands and 18-carat gold appliqués underscore the maritime character of this timepiece. The IWC-manufactured 82835 calibre features a Pellaton winding system. Fitted with ceramic components, it boasts a power reserve of 60 hours

Calibre Family 82000

The IWC-manufactured 82000 calibre ties in with the tradition of high-quality automatic movements from IWC. It is fitted with the highly efficient IWC Pellaton automatic winding system, which uses both directions of the rotor to wind the mainspring. As in the IWC-manufactured 52000 calibre family, components in the system subject to pronounced stress, such as the pawls, the automatic wheel, or the cam, are made of ceramic. Thanks to the use of this high-tech material, they are virtually wear-free. The efficient automatic winding system builds up a power reserve of at least 60 hours in the mainspring. The indexless balance with a flat coil oscillates at a frequency of 4 hertz (28,800 beats per hour), ensuring a high level of precision. The rotor is skeletonised and offers a view of the movement decorated with circular graining and Geneva stripes.

Tide Indication

The tides are a timelessly fascinating spectacle: twice a day, the waves retreat from the shore before inexorably rising again. This natural phenomenon is caused by a complex interplay between the gravitational and centrifugal forces of the moon, the earth and the sun. The time between two high tides is precisely 12 hours and 24 minutes. If, for example, it is high tide at midnight, the next high tide will occur at 12.24. The Portugieser Yacht Club Moon & Tide shows the slightly shifting time for the next high tide on the dial. During the 12 hours and 24 minutes between two high tides, the display disc will rotate by around 24 minutes on its 12-hour scale. The energy required is channelled from the base movement’s hour pinion. A precisely calculated reducing gear comprising three cogs slows the rotation to the point where the tidal disc rotates around its axis once in exactly 14.76 days. The tidal display module is integrated into the 82835 calibre movement and contains 49 parts.

The Portugieser Yacht Club

Since 2010, the Portugieser Yacht Club has brought a sporting note to the family. As a nautical sports watch, it combines timeless elegance with ruggedness and high water-resistance. These characteristics make the Yacht Club an extremely versatile watch that cuts a fine figure on both water and land.

About IWC Schaffhausen

In 1868, the American watchmaker and entrepreneur Florentine Ariosto Jones travelled from Boston to Switzerland and founded the “International Watch Company” in Schaffhausen. His visionary dream was to combine advanced American manufacturing methods with the craftsmanship of Swiss watchmakers to make the best pocket watches of his time. In doing so, he not only laid the foundation to IWC’s unique engineering approach but also established the centralized production of mechanical watches in Switzerland.

Over its 150 year history, IWC Schaffhausen has developed a reputation for creating functional complications, especially chronographs and calendars, which are ingenious, robust and easy for customers to use. A pioneer in the use of titanium and ceramics, IWC today specializes in highly engineered technical watch cases manufactured from advanced materials, such as titanium-aluminide and Ceratanium®. Preferring the principle of “form follows function” over decoration, the Swiss watch manufacturer’s timeless creations embody their owners’ dream and ambitions as the journey through life.
