The Portugieser IW5703-02, seen from the bench
The Portugieser IW5703-02 is the contemporary evolution of an icon born in 1939 as a maritime navigation instrument. Featuring a 42mm stainless steel case, this model preserves the chronometric heritage of Schaffhausen through rigorous proportions and uncompromised legibility. The watch is powered by the proprietary IWC 62060 caliber, a manual-winding movement embodying Swiss manufacturing precision. The 20mm lug width is the spatial interface defining the relationship between the watch case and the wrist, engineered as a compromise between case presence and classical strap proportion.
