The IWC Portugieser Chronograph IW371620 is the white-dial, blue-subdial version of IWC’s 41 mm stainless-steel chronograph, announced in August 2022. It pairs the contrast-rich dial with IWC’s automatic caliber 69355, a 46-hour power reserve and a 3 bar water-resistance rating. Here are the exact-reference details, with manufacturer specifications distinguished from retailer price snapshots.
What is the IWC Portugieser Chronograph IW371620?
IW371620 is a Portugieser Chronograph in stainless steel with a white dial, contrasting blue subdials and blued hands. IWC announced the white-and-blue Portugieser models on 15 August 2022. This is an exact-reference overview; specifications and styling can differ across other Portugieser Chronograph references.
IWC’s 15 August 2022 announcement identifies the white-and-blue treatment and the chronograph layout: the minute counter is at 12 o’clock and small seconds at 6 o’clock.
Design and dimensions
IWC specifies a 41 mm case diameter and 13 mm case height. The case is stainless steel, and the convex sapphire crystal has antireflective coating on both sides. The dial’s blue counters and hands provide the main contrast against the white background.
#1 Best Overall

The manufacturer lists a 20 mm strap width. A retailer listing describes this reference with a blue rubber strap, but the IWC product page does not establish a specific replacement strap SKU. Treat 20 mm as a measurement starting point, not confirmation that every strap, clasp or end fitting will fit.
Caliber 69355 and chronograph functions
Inside is IWC-manufactured automatic caliber 69355. IWC lists a 46-hour power reserve, a frequency of 28,800 vibrations per hour (4 Hz), 27 jewels and 205 components. The stated chronograph functions are minutes and seconds; the feature list also includes small hacking seconds. IWC’s launch release describes a column-wheel chronograph design and a sapphire display back.

These are manufacturer specifications and descriptions, not independent accuracy or power-reserve test results. No such testing is established here.
Water resistance and everyday considerations
IWC rates the IW371620 to 3 bar. That is the manufacturer’s stated rating; it does not, by itself, establish suitability for swimming or diving. The cited product specification gives the rating, not a tested activity profile.
