This IWC Portugieser Chronograph, reference 3714, is a luxury automatic wristwatch crafted from 18k yellow gold. The timepiece features a white dial with applied gold-tone Arabic numerals, reflecting the design lineage of the classic oversized IWC marine-inspired chronometers first introduced in the late 1930s.

It is equipped with a functional chronograph complication, powered by an automatic International Watch Co. movement, calibre C.79350. The round case measures approximately 41 mm in diameter and includes a gold buckle. The case back bears various hallmarks, including the International Watch Co. brand name, the gold fineness mark 750, a unique serial number, and Swiss hallmarks. The watch is presented on a black leather strap, with additional straps included.

The total gross weight of the piece is approximately 69.15 dwt. As a hallmark of modern IWC horology, this model balances classic aesthetic proportions with a sophisticated automatic chronograph mechanism, serving as a contemporary interpretation of the historic Portugieser collection. The design is marked by its high legibility and clear, balanced dial layout, which has become a signature element of the model line.
