The never-ending dance of the sun and the moon, captured on the dial of a watch: The Portofino Automatic Day & Night 34 is the first 34-millimetre Portofino model to feature a charming day & night complication. A small disc at 6 o’clock indicates whether it is currently day or night. At noon or midnight, the sun or the moon will appear in the upper area of the display.
