IWC Portugieser Annual Calendar 44mm Mens Watch IW503502

Technically and aesthetically ahead of its time, the IWC Portugieser collection has become truly iconic – delivering high precision timekeeping on land and at sea.

Presented within a 44.2mm stainless steel case, this IWC Portugieser Annual Calendar Watch is characterized by its rich blue dial, with an annual calendar at 12 o’clock indicating the month, date and day in three separate windows.

Powered by a reliable, 52850 caliber with a 7-day power reserve, IWC-manufactured movement, the dial also presents a power reserve display, two chronograph sub-dials, Arabic numerals and small hacking seconds.

An anti-reflective, arched-edge sapphire crystal glass provides enhanced protection and creates a slender silhouette, while the transparent, sapphire glass back reveals the working of the inner workings of the timepiece.

Water resistant to 30 meters, a black alligator leather strap completes the look, with curved strap horns providing enhanced comfort on slimmer wrists.
