The Tonda Métropolitaine signature design element is the case made of steel, which is for its look as much as its modernity, with taut lines and a silhouette finer than those of the other great classics from the Manufacture. The subtlety of the design is accentuated by an asymmetrical case that flies in the face of convention. The drop-shaped lugs on the left profile are a hallmark of the brand, with perfect lines inspired by the golden ratio. To the right, the lugs extend to encompass the space around the crown, ensuring that this profile stands out.

On the Tonda Métropolitaine dial, all the information required for a woman in and of her time is clear to see, with indications of hours and minutes, a small second at 6 o’clock, and the date via a wide aperture. This distinctiveness, which is characteristic of the Parmigiani Fleurier style, is practical and most suitable for everyday use of the model, yet brings a touch of elegant originality too.

The elegance of the model is enhanced by the refined appearance of the dial. Its graphic simplicity is conveyed through a wide choice of colours and materials. The dial has a discreet finish known as flinqué. This pattern of concentric waves softens the modern lines of the watch, yet allows for its femininity to reassert itself. The brand's logo majestically sets itself apart in an oval cartouche, while delicately inlaid indices and Arabic numerals mark the hours.
