IWC’s new Portugieser Yacht Club Moon & Tide features a neap tide moon phase display for both hemispheres coupled with a high and low tide indicator function.

Presented in a 44.6 mm x 14.4 mm 18K red gold case with a blue sunburst dial and strap, the Portugieser Yacht Club Moon & Tide has a sophisticated mechanism developed by IWC which simplifies tides into high or low, and also whether they are neap or spring tides, via two displays, one at 12 o’clock and one a 6 o’clock.

Neap tides are the tides with the least difference between the high and low tides. They are the two lowest high tides of the month. Conversely, spring tides, a tide just after a new or full moon, have the greatest difference between high and low water.

In addition to the strength of the tide, the display at 12 o’clock also shows the moon phases in both hemispheres (simultaneously).

Gold-plated leaf-shaped center-mounted luminescent hands display the hours and minutes, while a long gold-plated baton-shaped red-tipped hand shows the seconds. There’s a color-matched date indication at 3 o’clock.

The flange is gold-colored and has a 0-60 graduated seconds scale. Inside of this on the dial is a white printed railroad minute track with applied gold luminescent rectangular hour indices, and inside of that are gold printed Arabic numerals (except at 12 and 6 o’clock).

Animating the time functions and tide indicator is IWC’s caliber 82835 which has a Pellaton winding system fitted with ceramic components and is good for a power reserve of 60-hours. The movement has a skeletonized rotor, chamfered edges, Geneva striping, and a perlage decoration. The free-sprung balance wheel oscillates at 4Hz is mounted on a non-traversing balance bridge.

Completing the fashionable and luxurious new Portugieser Yacht Club Moon & Tide is a blue rubber strap with a textile inlay and 18K red gold buckle. (Ref. 344001
