IWC Portugieser IW390701 44.6 mm Blue Dial

IW390701 places the Portugieser flyback chronograph in its most expansive, polished setting here. The blue dial and stainless-steel bracelet give the 44.6 mm case a confident, contemporary presence, while the see-through back preserves the collection's interest in mechanical display. Its 100-metre water resistance adds practical breadth to a watch whose visual language remains distinctly refined.

Inside, calibre 89361 combines an in-house automatic chronograph with flyback reset, small seconds and date indication. The movement measures 30 mm across and 7.5 mm high, with 38 jewels and 299 components. A single barrel provides 68 hours of power reserve, and the balance works at 4 Hz. The 14.3 mm case gives the movement and its displays ample room without making the design feel disjointed.
