The IWC Portofino IW510103 is the technical flagship of the Portofino collection, a line originally inspired by the relaxed, luxury lifestyle of the Italian Riviera. Encased in a polished 45mm stainless steel frame, this timepiece combines understated dress watch aesthetics with serious mechanical muscle.
At its heart lies the IWC-manufactured Calibre 59210, a robust manual-winding movement designed to run with chronometric precision for a full eight days (192 hours). To ensure absolute accuracy, the movement is engineered to run for nine days, but is mechanically stopped after eight to avoid the reduced torque of a winding-down mainspring. The movement’s exquisite “Côtes de Genève” finish and 30 jewels are visible through the transparent sapphire crystal caseback.
The silver-plated dial is a study in balance, featuring:
Functional Elegance: A power reserve indicator at 9 o’clock, a date display at 3 o’clock, and a small hacking seconds sub-dial at 6 o’clock.
Premium Details: Solid yellow gold-plated leaf-shaped hands and applied index markers that catch the light with every movement.
Signature Comfort: Paired with a dark brown alligator leather strap handcrafted by the renowned Italian leather goods house, Santoni, specifically for IWC.
This timepiece is water-resistant to 3 bar (30 meters) and features a scratch-resistant sapphire crystal with anti-reflective coating on both sides, ensuring durability and legibility for the modern collector in 2026.

This timepiece has undergone a thorough inspection of water resistance, accuracy, functionality and condition to determine the level of reconditioning required to meet our strict standards. It has also been referenced against technical documents and manufacturer records where available to ensure authenticity and a clean history.
