Anchored by the IWC calibre 69355 automatic movement — based upon the IWC 69370, housing 27 jewels across 194 parts, oscillating at 28,800 vph, and delivering a power reserve of approximately 46 hours — this Portugieser Chronograph brings together technical substance and refined design. A column-wheel mechanism governs the chronograph function, which is displayed across two sub-dials measuring 60 seconds and 30 minutes respectively.
The round, 41 mm stainless steel case measures 13.1 mm in thickness and features a fixed bezel, a pull/push crown, and a transparent case back. The scratch-resistant sapphire crystal protects a silver dial with blue leaf-style hands, Arabic numeral hour markers, and minute markers tracking the outer rim. A deployment clasp secures the blue alligator leather strap, sized at 20 mm width. Water resistance is rated to 30 meters / 100 feet.
Carrying the Swiss Made designation, this reference IW371605 belongs to IWC's storied Portugieser series and is presented complete with its original box and papers.
