IWC Portugieser IW371609 41 mm Black Dial

The black dial of IW371609 gives the Portugieser Chronograph a more graphic, disciplined appearance. Its 41 mm stainless-steel case and black alligator-leather strap form a continuous dark frame around the balanced timing layout, while the see-through caseback introduces a glimpse of the movement's finishing. The 13 mm profile keeps the watch substantial without losing the collection's tailored character.

Calibre 69355 is an in-house automatic chronograph with column-wheel control, small seconds and automatic pawl winding. It operates at 4 Hz and provides 46 hours of power reserve, with 27 jewels and 205 components housed in a 30 mm movement. The specification is compact enough for the case yet mechanically distinctive, giving the watch a focused, readable presence on the wrist.
