The IWC Portugieser Yacht Club Moon & Tide IW344001 is a 44.6 mm automatic watch in 18 ct 5N gold, with a blue dial and blue rubber strap. IWC’s English-language EU product listing gives a price of €46,100 including VAT; that is a regional list price, not a universal or guaranteed transaction price. Its tide indication and double moon display are the distinctive complications, while the movement is listed with a 60-hour power reserve.
Price and availability
IWC’s English-language EU product page lists the IW344001 at €46,100 including VAT. The figure applies to that regional listing; local pricing, tax presentation and stock may differ. Check IWC’s listing for the market where you intend to buy, since price and availability can change.
What the Moon & Tide indications show
Tide indication
IWC describes the tide indication as showing the arrival of the next high and low tide. The company calls it a newly developed feature and says the tide module is integrated into calibre 82835. Its complication explainer describes a 49-part module and a three-part reduction gear that makes the tide disc complete one rotation every 14.76 days. These are manufacturer-described mechanics, not an independent assessment of tide-prediction accuracy.
The indication is a feature of a mechanical wristwatch, not a replacement for a location-specific tide table or a navigation instrument. For planning an outing on the water, use appropriate local tide information.

#1 Best Overall
Double moon phase
The double moon display shows the current moon phase for the northern and southern hemispheres at the same time. IWC says its display deviates from the moon’s orbit by about 12 seconds per lunar month and requires a one-day correction every 577 years. Those precision figures are IWC’s claims for the mechanism.
