The IWC IW371606 was introduced in 2018 as part of the modern Portugieser Chronograph line. It belongs to the current generation Portugieser chronograph series that continues IWC’s established 40mm bi-compax layout format.
The IW371606 is built in a 40mm stainless steel case with a slim profile designed for the Portugieser large dial chronograph architecture. The case proportions are engineered to keep the dial visually open while maintaining balanced wrist presence.
The dial uses a silver toned base with applied Arabic numerals and leaf shaped hands. The layout follows a bi-compax chronograph configuration with a 30 minute counter at 12 o’clock and a running seconds sub dial at 6 o’clock, arranged symmetrically to maintain horizontal balance.
The chronograph function is integrated through a central seconds hand for elapsed time measurement, with sub dials dedicated to totalised timing. The design prioritises clear separation between time display and chronograph functions within a structured dial layout.
The watch is powered by the IWC automatic chronograph calibre 79350, based on a Valjoux architecture, operating with rotor driven self winding and a standard chronograph mechanism for daily use reliability.
A sapphire crystal protects the dial, and the watch is typically paired with a leather strap, consistent with its dress chronograph positioning.
The IW371606 follows the Portugieser design framework, which is defined by large dial architecture, symmetrical sub dial placement, and high legibility.
The chronograph layout is designed to maintain visual balance while preserving clear separation between running time and elapsed time functions. The applied numerals and leaf style hands reinforce the classical Portugieser design identity.
Within the IW3716xx family, this reference represents the stainless steel execution of the modern Portugieser Chronograph, positioned in the dress chronograph category rather than sport oriented chronographs.
The IW371606 is a 40mm stainless steel dress chronograph designed for balanced daily and formal wear use.
Its bi compax dial layout and central chronograph seconds hand provide standard elapsed time functionality with a clear and symmetrical display structure.
The automatic chronograph movement (Calibre 79350) offers self winding operation and conventional chronograph functionality designed for regular wrist wear.
In the pre owned market, evaluation typically focuses on dial condition, case finishing, chronograph function performance, and movement condition, all of which directly affect overall value and authenticity.
