IWC says the display shows the arrival of the next high and low tide, alongside a double moon phase for the northern and southern hemispheres and an integrated neap- and spring-tide display. The available official material establishes what the watch is designed to indicate, but not how to set it or how its readings compare with local tide tables.
What the Moon & Tide complication indicates
IWC describes the tide display as showing the arrival of the next high and low tide. The product listing also specifies a double moon phase for the northern and southern hemispheres and an integrated indication of neap and spring tides. IWC called this its first watch with a newly developed tide indication in the 24 April 2020 announcement.
Those descriptions establish the displayed information, not the mechanism’s operating details. The cited product material does not explain calibration, location settings, or accuracy against local tide tables, so the display should not be treated as a substitute for a local forecast on the basis of these sources alone.
IW344001 and IW344002 compared
The 2020 announcement identifies reference 344001. IWC’s current regional product listing also identifies a steel version, IW344002; it should not be assumed to have been part of that original announcement. Specifications below are from IWC’s product listings accessed in 2026, and availability varies by region.

What distinguishes the gold reference
The IW344001 pairs its blue dial and rubber strap with an 18 ct 5N gold case. IWC lists its automatic calibre 82835 with Pellaton winding, a 60-hour power reserve, and a date display. The listed case measures 44.6 mm across and 13.4 mm high, with water resistance of 6 bar.
IWC’s US page displayed a price of US$46,400 excluding VAT when accessed in 2026. That is a current listing price, not evidence of the watch’s 2020 launch price; pricing and availability can change.

What distinguishes the steel reference
IWC’s regional listing for IW344002 describes a stainless-steel case and bracelet, black dial, calibre 82836, and 10-bar water resistance. Its listed diameter is also 44.6 mm. These details are specific to that regional listing; it does not provide a comparable case height or power reserve in the cited material.
For a buyer comparing the two, the documented differences are case and bracelet materials, dial color, calibre, and water resistance. Check IWC’s listing for the relevant country before relying on local availability or price.

What the 2020 debut established
IWC announced the Portugieser Yacht Club Moon & Tide on 24 April 2020 and described it as the first IWC watch with its newly developed tide indication. In the same release, CEO Christoph Grainger-Herr said the Portugieser’s face had changed little over more than 80 years and described its design as remaining contemporary. That remark concerns the collection’s design, not the accuracy or performance of the tide display.
The official specifications make the Moon & Tide’s purpose clear: it combines tide and moon-phase information in a Yacht Club model. They do not provide a hands-on basis for judging wrist comfort, finishing, legibility, or real-world tide accuracy.
