IWC Watch Portugieser Annual Calendar. IW503502.

Lovers of rare and unique complications need look no further than this IWC Portugieser Annual Calendar watch. Powered by one of the brand’s legendary in-house movements, the men’s timepiece boasts an annual calendar display with the month, date and day presented in three separate, semi circular windows at 12 o’clock.  The IWC-manufactured 52850 calibre ensures the advanced mechanism automatically takes the length of individual months into account and requires manual correction via the crown only once a year at the end of February. If that wasn’t enough, the IWC Portugieser watch then showcases a fascinating 7 day power reserve which is displayed proudly on the dial at the 9 o’clock position, providing perfect symmetry to the small seconds on the left.

Each of these impressive complications are exhibited on a handsome blue sunray-finished dial detailed with greyed steel hands and classic Arabic numerals, all protected by arched-edge sapphire crystal glass treated with anti-reflective coating. The shape of the glass allows the case to look even slimmer on the wrist, enhancing it’s already stylish 14.9 millimetre height and 44.2 millimetre stainless steel diameter. The case promises a water resistance of 30 metres and is secured to the wrist by a luxurious black alligator leather strap and folding buckle. Turn the IWC Portugieser Annual Calendar watch over and admire the automatic winding movement further and watch as the Côtes de Genève decorated oscillating rotor spins with every flick of the wrist.
