IWC Portugieser Perpetual Calendar 42mm Steel IW344203

The IWC Portugieser Perpetual Calendar 42 IW344203 brings IWC’s most prestigious calendar complication to accessible stainless steel. The 42.4mm case measures 13.8mm thick, with a see-through sapphire glass back and convex sapphire crystal with antireflective coating on both sides. The silver-plated dial offers a clean, classic backdrop.

Inside beats the Calibre 82650 automatic movement with approximately 60 hours of power reserve, powering the perpetual calendar mechanism in a slimmer, more wearable package than the 44.2mm variants. The display presents hours, minutes, and small seconds in IWC’s characteristically elegant layout.

Presented on a black alligator leather strap by Santoni, this stainless steel Portugieser Perpetual Calendar 42 offers the ultimate combination of grand complication and everyday practicality. Water resistant to 3 bar.
