DescriptionThe IWC Portugieser Perpetual Calendar Ref. IW503404 is a marvel of haute horlogerie, encapsulating luxury and intricate watchmaking. The watch's 18 ct 5N gold case, measuring 44.2 mm in diameter, presents an air of understated sophistication, perfectly complemented by the refined black alligator leather strap crafted by Santoni. The case's 14.9 mm height is not just about its commanding presence; it's a space that accommodates the sophisticated 52615 Calibre movement. The see-through sapphire glass back offers a glimpse into the heart of the watch, revealing the intricate details and the meticulous craftsmanship of the movement, a hallmark of IWC's unparalleled expertise. The water resistance of up to 3.0 bar adds to its practicality, ensuring durability and reliability.

At the core of this exquisite timepiece is the 52615 Calibre, an IWC-manufactured movement that stands as a testament to the brand's commitment to precision and quality. This self-winding mechanism, composed of 381 components and 54 jewels, operates at a frequency of 28,800 VPH (4 Hz), ensuring impeccable timekeeping. The remarkable 168-hour (7-day) power reserve is a nod to its efficiency and reliability. The perpetual calendar is a standout feature, mechanically programmed to accurately track the date, day, month, and year for 577 years, alongside a perpetual moon phase display for both the northern and southern hemispheres. This complication not only showcases the technical ingenuity of the watch but also adds a level of celestial elegance. The arched-edge, antireflective sapphire glass ensures clarity and resilience. The IWC Portugieser Perpetual Calendar Ref. IW503404 is more than just a timekeeper; it's a masterpiece of horological artistry, designed for those who appreciate the seamless blend of traditional luxury and advanced watchmaking technology.
