Since 1868 Swiss watch manufacturers IWC Schaffhausen have been creating masterpieces of haute horlogerie that combine precision engineering with exclusive design. Over the years, their straightforward, no-nonsense style has appealed to adventurers far and wide.


IWC has referred to their Portuguese Chronograph as a “machine for modern time travelers.” Indeed, this sophisticated and refined timepiece recalls the wonder of Portugal’s seafaring past.


IWC’s Portuguese 3714 series are sought after timepieces. This model possesses a mechanical movement with automatic winding, and features IWC’s Caliber C.79240, 31 jewels, 28,800 vph, and a 44-hour power reserve. The high-polished stainless steel case measures 41 mm in diameter (excluding lugs, pushers, and crown), is 12.3 mm in height, and rests upon a black matte alligator leather strap with a brushed stainless steel post buckle. The solid case back is screwed-on and is water-resistant to 30 m / 3 atm.

Standout feature(s): clean uncluttered design, subtle and refined silvered sub-dials and applied gold-tone Arabic numerals and leaf-shaped hands.
