IWC Portugieser Yacht Club Moon & Tide Black Dial Stainless Steel Case 44.6mm - IW344002

The first Portugieser, Reference 325 from 1939, was inspired by IWC Schaffhausen’s deck observation watches – nautical instruments used to perform navigational tasks on ships. This heritage is reflected by the Portugieser Yacht Club, which has brought a hint of sportiness to the collection since 2010. The Portugieser Yacht Club Moon & Tide is the first stainless steel model to feature the IWC-developed tide indication. Located at 6 o’clock on the dial, it informs about the expected times for the next high and low tide. Another feature is the Double Moon™ indication at 12 o’clock, which shows the moon phase as seen from the Northern and Southern hemispheres and will only deviate by one day after 125 years. The display has been enhanced to show spring and neap tides, indicating the strength of the current tides. The black dial is made in an intricate process comprising 60 individual steps. Thanks to the application of 15 layers of transparent lacquer, it emanates tremendous visual depth. The watch features a polished stainless steel case with a diameter of 44.6 millimeters and rhodium-plated hands and appliques. The transparent sapphire glass case back showcases the IWC-manufactured 82836 caliber with a Pellaton automatic winding system and ceramic components. This nautical sport watch is fitted with a stainless steel bracelet with brushed H-links and polished center links.
