Review: The New IWC Portugieser Eternal Calendar
When one thinks of IWC, the image of 'pilot’s watches' immediately springs to mind. However, another iconic feature of the brand that cannot be overlooked is the cruciform layout of its perpetual calendar displays. Developed by the renowned Kurt Klaus in the early 1980s, the perpetual calendar mechanism revolutionized the brand and paved the way for high watchmaking. The mechanism, known internally as “Operation Eternity”, made its debut in the Da Vinci Perpetual Calendar in 1985 and has since been continuously enhanced and refined.
The Evolution of IWC’s Perpetual Calendar
Over the years, IWC has continued to innovate and improve upon its perpetual calendar mechanism, introducing groundbreaking timepieces like the Perpetual Calendar Digital Date-Month and the Portugieser Perpetual Calendar with a double-moon display. This year, IWC has taken a significant leap forward with the introduction of the new Portugieser Eternal Calendar, featuring a super perpetual calendar that requires no adjustments for at least a thousand years.
The case of the Portugieser Eternal Calendar is crafted from platinum, giving it a luxurious and timeless appeal. Measuring 44.4mm x 15mm, the case is slightly larger than its predecessor, the Portugieser Perpetual Calendar, but retains a classic and elegant design. The front-and-back box sapphire crystals add a neo-vintage touch to the timepiece, reminiscent of traditional pocket watches.
Aesthetic Enhancements
One of the most notable changes in the Portugieser Eternal Calendar is the dial. The use of glass, frosted and lacquered white, for the main dial, creates a unique and refreshing look. The addition of separate glass sub-dials for the displays of the secular calendar adds depth and complexity to the dial, though it may impact legibility. The various sub-dials house different functions, such as the perpetual moon phase display, date, month, day, and power reserve indicators.
The Calibre 52640, the heart of the Portugieser Eternal Calendar, is a marvel of engineering. The super-accurate perpetual calendar, known as the secular calendar, sets new standards in precision timekeeping. By integrating a 400-year wheel into the perpetual calendar module, IWC ensures that the calendar remains accurate for centuries to come. The moon phase indicator is equally impressive, deviating from the moon’s actual orbit by just one day after 45 million years.
Conclusion
The IWC Portugieser Eternal Calendar is a testament to precision watchmaking and innovation. While the price may seem considerable, the technical prowess and craftsmanship that went into creating this timepiece justify its value. With its unique features and exceptional accuracy, the Portugieser Eternal Calendar sets a new standard for perpetual calendar watches.
For those looking for alternatives, IWC's existing perpetual calendar watches offer a blend of functionality and reliability. The brand's commitment to excellence is evident in timepieces like the Big Pilot’s Watch Perpetual Calendar Top Gun Lake Tahoe. Additionally, for connoisseurs seeking unparalleled precision, the Andreas Strehler Lune Exacte provides a compelling option with its advanced moon phase indicator and exquisite finish.
In conclusion, the IWC Portugieser Eternal Calendar is a remarkable timepiece that pushes the boundaries of traditional watchmaking. With its innovative features and exceptional accuracy, it is sure to captivate watch enthusiasts and collectors alike.
