Parmigiani Fleurier PFC914-1020021-100182 Tonda PF Micro-Rotor 40mm Stainless Steel Golden Siena Watch

The Parmigiani Fleurier Tonda PF Micro-Rotor PFC914-1020021-100182 — the Golden Siena — pairs the ultra-thin micro-rotor movement architecture with a warm golden dial inspired by the terracotta tones of the Tuscan city. Case Shape: Round. At 7.8mm thin, this is one of the most elegant slim automatic watches produced by any independent Swiss manufacturer, its platinum micro-rotor entirely integrated within the movement height to achieve a slimness that a conventional automatic rotor cannot permit.

The Platinum Micro-Rotor — A Technical Achievement

The platinum micro-rotor of Calibre PF703 is a component of exceptional engineering — small enough to integrate within the height of the 3.07mm movement rather than sitting above it, yet dense enough (platinum being the heaviest of all precious metals) to wind the mainspring with the same efficiency as a larger rotor. The result is a movement just 3.07mm thick that achieves a complete watch height of 7.8mm — among the slimmest automatic references in the Parmigiani collection.

The Golden Siena Dial

The warm golden tone of the Siena dial references the characteristic terracotta and honey-gold architecture of the medieval Tuscan city — a colour that shifts between amber and gold depending on the light. Grain d’orge hand-guilloché finishing adds tactile depth to the warm surface. Applied 18ct gold rhodium-plated indices, stainless steel bracelet, sapphire caseback. Water resistant to 100 metres.
