Quietly refined, this Tonda PF Micro-Rotor distills Parmigiani's contemporary dress-sport language into a notably slim stainless steel 40mm case. The Golden Siena dial gives the watch its warmth and character, balancing the restraint of the monochrome metal case and bracelet with a richer, more nuanced tone. Inside is an automatic micro-rotor movement, a fitting choice for a profile just 7.8mm thick. On the wrist, it wears with the sleek, composed feel collectors expect from the Tonda line.
