IWC Portofino IW510102 45 mm Black Dial

IW510102 explores the Portofino collection's large-format dress language through a 45 mm stainless-steel case that is only 11.7 mm thick. The black dial, dark brown Santoni alligator-leather strap and power-reserve display give the watch a sombre, carefully arranged character. A solid caseback keeps the presentation discreet, while the 30-metre water resistance reflects its primarily formal orientation.

The hand-wound calibre 59210 provides 192 hours of power reserve, small seconds and a date display. IWC Schaffhausen's movement measures 37.8 mm in diameter and contains 215 components with 30 jewels, operating at 4 Hz. The large movement gives the broad case genuine mechanical weight rather than relying on size alone.
