The Portugieser IW5463-05 (aka: IW546305), seen from the bench
The Portugieser IW5463-05 is a 43 mm red gold case watch representing the contemporary evolution of a 1939 design. It features the IWC 98900 calibre, a manual-winding mechanical movement with tourbillon escapement operating at 4 Hz. The white dial displays Arabic numerals and blued hands. The case lug width is 20 mm. This model embodies German watchmaking precision applied to Grande Horlogerie, with visible movement through a sapphire caseback revealing finished plates and Breguet balance spring.
