The IWC Portugieser Yacht Club Moon & Tide Ref. IW344001 combines refined nautical styling with an innovative mechanical complication developed specifically for the collection. Its 44.6 mm case is crafted from 18-carat 5N gold and paired with a rich blue dial and blue rubber strap, creating a sophisticated yet sporty aesthetic. The watch features a newly developed tide indication alongside a double moon-phase display for the northern and southern hemispheres, including an integrated indication of neap and spring tides. Convex sapphire glass with antireflective coating on both sides protects the dial, while central hacking seconds, a date display and a screwed-in crown add practical functionality.

The timepiece is powered by IWC-manufactured Calibre 82835, an automatic, self-winding movement equipped with the Pellaton winding system and a 60-hour power reserve. Operating at 28,800 vibrations per hour (4 Hz), the movement consists of 234 components and 25 jewels and is finely decorated with Côtes de Genève and Perlage. The 44.6 mm case measures 13.4 mm in height and offers 6 bar of water resistance, while the movement can be admired through the synthetic sapphire crystal case back. With its precious 18-carat 5N gold construction, sophisticated tide and moon-phase indications, and distinctive maritime character, the IW344001 is an exceptional expression of IWC’s technical expertise and luxury sports-watch design.
