IWC Portugieser Annual Calendar IW503504

Though they were not a mainstay of the company's catalogue until the 1990s, IWC's Portuguese watches originated as consummate maritime chronometers in the early part of the 20th century, and have established a long and outstanding history of both mechanical and design elegance. Now, the Portuguese has been united with an unusual and prestigious horological complication, the annual calendar. Taking form in three outstandingly easy-to-read windows at the top of the dial, this function is as elegant in its display as it is mechanically difficult to achieve. The result is a lot less clutter than many calendar watches. There's also an ingenious seven-day power reserve.

This IWC Portugieser Annual Calendar IW503504 has a Silver Arabic dial and a Leather strap. This IWC has undergone a thorough inspection of accuracy, functionality and condition at our IWC certified service centre to determine the level of reconditioning required to meet our strict standards. It has also been checked against our records to ensure authenticity. All our watches have a 24-month warranty for your peace of mind.
