The OW P-104 Selectron is a contemporary Swiss mechanical watch that revives the spirit of Ollech & Wajs’ historic “wrist computer.” It is built around a robust stainless-steel case with 300 meters of water resistance and powered by the Soprod Newton automatic movement. Its defining feature is the bi-directional logarithmic bezel, which allows the wearer to perform calculations such as conversions, ratios, and multiplications without electricity or batteries. This makes it both a professional tool and a collector’s piece, blending vintage ingenuity with modern reliability.
