The IWC Portugieser collection is celebrated for its balance of elegant design and technical prowess, with the IWC Portugieser Perpetual Calendar 44 (IW503701) exemplifying this blend. Crafted to embody both sophistication and functionality, the IW503701 is a masterpiece that caters to serious watch enthusiasts and collectors who appreciate the art of fine horology.
Boasts a 44.2mm stainless steel case, a more refined take compared to some of its gold or platinum counterparts. Its dial is a striking midnight blue, enriched with silver-plated subdials that add an understated luxury feel, allowing for excellent legibility. The clean, symmetrical layout of the perpetual calendar displays—day, date, month, and year—is a hallmark of IWC’s design prowess.
The watch also features a moon phase indicator, with a dual hemisphere display showing the moon phase for both the northern and southern hemispheres. This thoughtful detail underscores the brand’s global appeal.
Powering the IW503701 is IWC’s in-house calibre 52610, an automatic movement that integrates IWC’s signature Pellaton winding system. Known for its durability and efficiency, this system is further enhanced with ceramic components, reducing wear and tear and ensuring a longer life. The movement offers a seven-day power reserve, which is a practical feature for those who may rotate their watches but still expect it to keep time precisely.
The perpetual calendar complication is accurate until 2100, a testament to the meticulous engineering that goes into each piece. This means the wearer won’t need to adjust the date, even in leap years, which is a significant convenience for a mechanical watch. The moon phase display only needs correction once every 577 years, showcasing the watch’s long-term precision.
Despite its substantial size, the IW503701 sits comfortably on the wrist, thanks to the curved lugs and ergonomic design. The watch is paired with an elegant black alligator leather strap, which complements its refined aesthetic while providing a comfortable fit.
The IW503701 is water-resistant up to 30 meters, making it splash-resistant but not ideal for swimming or diving. However, as a dress watch with an emphasis on luxury and sophistication, it is more suited for formal occasions rather than rugged use. The durable materials and meticulous finishing ensure that this watch will age gracefully, becoming a cherished piece in any collection.
