Introducing IWC Portugieser Yacht Club Moon & Tide Men’s Watch Replica IW344001

The IWC Portugieser replica was born in 1939 following a request from two Portuguese navigators and businessmen – Rodrigues and Teixeira – who wanted the precision of a marine chronometer in a wristwatch format. No need to say that this iconic IWC collection has strong ties to the nautical world. And to celebrate these roots, IWC is unveiling a new model today with an unprecedented complication that couldn’t be more appropriate: a tide indication. Encased in a sporty and large case, meet the new IWC Portugieser Yacht Club Moon & Tide 44.6mm watch replica IW344001.


The IWC Portugieser Yacht Club blue dial watch fake is a sports model in this rather elegant collection, with its nautical, yachting, regatta-ready note. More robust, larger, a bit more rugged and bulky, it has mostly favoured one complication until now, the chronograph – a world timer has also been available in the past. A versatile watch, capable of timing a sailing race but also at ease with a drink at the marina. In addition to the revamped chronograph collection, also introduced as part of the 2020 line-up, the Schaffhausen-based brand is also unveiling a brand new complication, with deep nautical roots: the new Portugieser Yacht Club Moon & Tide fake.

44.6mm Case

Visually, there’s not much that changes compared to the rest of the Yacht Club collection. We find the same 44.6mm case, here crafted in 18k rose gold (the only version available for the moment), with crown guards, robust lugs and a thin polished bezel opening on a large dial. In the same vein, the dial retains the classic leaf-shaped Portugieser hands, yet bolder and with lume, the railroad minute track with applied lume plots and signature Arabic numerals. Complementing the nautical look, this IWC Portugieser Yacht Club Moon & Tide replica comes on a blue rubber and textile strap that the collection has become associated with. Of course, the buckle matches the red gold case here.

Blue Sunray-brushed Dial

What changes, however, is the display. Instead of the chronograph, there is now a novel indication, based on two sub-counters, linked to moon phases and tide calculations. A sub-dial at 6 o’clock indicates the expected times for the next high and low tide. The double moon phase display at 12 o’clock (with both hemispheres indicated) has been enhanced to show spring and neap tides and thus provides information about the strength of the current tides.

The dial of this new IWC Portugieser watch replica IW344001 has a blue sunray-brushed base with rose gold contrasting elements for the hands, the indexes and the secondary indications – a classic combination for IWC. Not to obscure the lower sub-dial, the date is positioned at 3 o’clock. IWC paid attention to the details here, with guilloché work, gold accents, and an applied gold plate around the circumference of the 6 o’clock subdial. As far as legibility goes, there is double-sided AR coating on the convex sapphire crystal, something I always appreciate.

Calibre 82835 Movement

To power this new watch replica, IWC relies on its 82000-series base movement. The tidal display module is integrated into the novel calibre 82835 and contains just 49 individual parts. The base movement is familiar and boasts 60h of power reserve, features the Pellaton winding system and beats at 4Hz. It is visible through a sapphire display caseback and is finished in a pleasant way, with opened bridges that reveal most of the parts – including the ceramic, wear-free wheels.

It takes 24 hours and 48 minutes for the earth and moon to be in the same position, meaning that the time between two high tides is always 12 hours and 24 minutes. To measure the tides, IWC added a 49-part module to its 82835 calibre movement. Installing a three-cogged reducing gear to the hour pinion slows down the rotation of the tidal discs, allowing the disc to rotate around its axis every 14.76 days. Note that the time of the next tide is always approximate due to the fact that the discs are continually moving. So, if you’re checking at 10 o’clock AM and the indicator points to 12 o’clock, the tide will actually be slightly after 12. This discrepancy comes out to 10 minutes over 100 years.
