IWC Portofino IW391502 39 mm

IW391502 brings a lighter, more compact expression to the Portofino chronograph family. The 39 mm stainless-steel case and white dial create a bright, composed foundation, while the beige calfskin strap introduces a gentle contrast and a quick-change system. A see-through back adds a discreet mechanical accent, and the 50-metre water resistance makes the watch more versatile than its elegant proportions might suggest.

Inside, IWC calibre 69355 is an in-house automatic chronograph with small seconds. Its column-wheel control and automatic pawl winding sit within a 30 mm movement containing 205 components and 27 jewels. The 4 Hz calibre provides 46 hours of power reserve. At 13 mm thick, the case retains enough presence for the chronograph display while remaining notably more wearable than larger Portofino timing references.
