Tide Display - IWC Portugieser Yacht Club Moon & Tide Watch

This is IWC's first watch equipped with a tide display function, and it is also the most important new piece in this year's "Portugal" series. It takes into account both beauty and practicality - there is a tide display panel at 6 o'clock on the dial, and the outer ring is marked with 12 hours. The scale can be used to predict the next high tide time through the red arrow pointer, and the approximate time of low tide can also be easily read.

According to the fixed cycle of sea water rising tide - 12 hours and 24 minutes, the tide display disc of this watch rotates for about 24 minutes in each cycle. In order to transmit the kinetic energy of the travel time gear train to the tidal disk, IWC specially developed a reduction gear train, consisting of a total of 49 parts, ensuring that the tidal disk's rotation time is accurate to 14.76 days, with a theoretical error of only 10 minutes per 100 years.

Another major feature of the new watch is the dual moon phase display, which indicates the strength of the current tide based on the profit and loss of the moon phase - during the full moon and new moon, the earth, moon and sun are in a straight line, and the tidal forces are superimposed at this time to form Spring; During the waxing and waning phases of the moon, the relationship between the sun and the moon is at right angles, and the resulting tidal force is weak, forming a Neap.

The 44mm red gold case is equipped with Caliber 82835 automatic winding movement, equipped with a Pellaton automatic winding system, with a swing frequency of 28800vph and a power reserve of 60 hours. Comes with a blue fabric lined rubber strap.
