The IWC Shaffhausen Portugieser Eternal Calendar with Moon Phase

In the realm of haute horlogerie, the IWC Schaffhausen Portugieser Eternal Calendar with Moon Phase stands as a testament to precision engineering and aesthetic elegance. This timepiece sets a new benchmark with its moon phase accuracy of an unprecedented 45 million years, eclipsing previous records. The distinction of an Eternal Calendar lies in its intricate mechanical programming, which negates the need for manual corrections for leap years until the year 3999, a feat that traditional perpetual calendars cannot match without three adjustments every 400 years.

The marvel of this watch is further accentuated by its minimalist mechanics, comprising merely eight parts, a testament to IWC Schaffhausen’s mastery in watchmaking. The moon phase complication, a signature of IWC, is rendered with exceptional beauty and precision, showcasing the lunar cycle as observed from both hemispheres through a Double Moon display. Achieving this level of accuracy involved leveraging a supercomputer to simulate over 22 trillion combinations, ensuring the moon phase’s meticulous precision.

Housed within this horological masterpiece is the IWC-manufactured calibre 52640, pulsating at a frequency of 28,800 vph / 4 Hz and boasting a robust 7-day power reserve. Encased in platinum and adorned with a glass dial featuring white lacquer, rhodium-plated hands, and appliqués, the watch exudes luxury. The black alligator leather strap from Santoni, coupled with a platinum folding clasp, complements the watch’s grandeur. Despite its complex inner workings, the Portugieser Eternal Calendar maintains a slim profile at 44.4 mm in diameter and 15 mm in thickness, a remarkable achievement for such a sophisticated mechanism.

Unveiled at Watches and Wonders 2024 in Geneva, the Portugieser Eternal Calendar is not just a timepiece; it’s a celebration of IWC Schaffhausen’s relentless pursuit of horological perfection. For aficionados and collectors, this watch represents the pinnacle of mechanical innovation and design finesse. For more information on this engineering marvel, check out this link for more info!
