IWC Portugieser Chronograph IW371620 41mm Stainless Steel Blue Rubber Strap (Calibre 69355)
The IWC Portugieser Chronograph IW371620 is a 41mm stainless steel automatic chronograph powered by the in-house Calibre 69355 with a 46-hour power reserve, finished with a blue rubber strap and a sapphire display caseback, plus 30m water resistance and an IWC warranty that can extend up to 8 years with Care registration.
The IWC Portugieser Chronograph (Ref. IW371620) is a clean, classic chronograph that still feels modern enough for daily wear. The 41mm steel case hits a very wearable size, and the sapphire glass back is a nice upgrade if you enjoy seeing the movement in action. What makes this specific reference stand out is the blue rubber strap, which gives the Portugieser a sportier edge while keeping the overall look tidy and refined. It’s a good setup if you want one watch that can move between office days and weekends without feeling out of place.
Inside is the IWC-manufactured Calibre 69355, an automatic chronograph movement designed for reliable everyday use with a 46-hour power reserve. Water resistance is 3 bar (30 meters), so it’s fine for light splashes, but it’s not a swimming watch. Warranty-wise, it typically comes with 2 years, and you can extend coverage up to 8 years by registering through the IWC Care program.
