IWC Portugieser
A large wristwatch with a pocket-watch movement, ordered by two Portuguese watch dealers.
The dealers Rodrigues and Teixeira ordered wristwatches in the late 1930s that were as accurate as marine chronometers. IWC put a pocket-watch movement in a large case. The model was long made in small series and became widespread only in the 1990s.
Materials: Steel or gold; hand-wound pocket-watch movement
Manufacture: Made in Schaffhausen; the movement was made for pocket watches.
The large, plain dial with Arabic numerals.
The small seconds on its own subdial at six.
