Parmigiani Fleurier Tonda PF Sport Chronograph PFC931-1020021-400182

The core technical highlight of the Parmigiani Fleurier Tonda PF Sport Chronograph (Ref. PFC931-1020021-400182) lies in its Ultra-Cermet case. Cermet is essentially a composite material formed by combining ceramic and metal. Compared to traditional ceramics, it offers exceptional hardness and scratch resistance while retaining the refined light-reflecting qualities of metal. This explains why Ultra-Cermet does not look like standard black ceramic; instead, it resembles titanium from certain angles, while displaying a soft luster akin to sandblasted platinum from others. The true complexity lies in the fact that Parmigiani does not limit the use of this material to the watch case alone; the case middle, bezel, chronograph pushers, and crown are all crafted from this all-metal cermet. The assembly process takes a full day and involves 72 individual components.

With a 42.5mm diameter and a thickness of 13.3mm—combined with the fact that Ultra-Cermet is significantly lighter than traditional stainless steel—the watch feels noticeably lighter on the wrist than many other chronographs of similar dimensions. This advantage of reduced weight becomes particularly apparent during extended periods of wear.

The "London Grey" dial is arguably one of the finest grey dials in the realm of high-end sports watches today. It utilizes a specialized metallic surfacing technique that combines 9K gold with nickel. The defining characteristic of this process is its ability to produce subtle tonal shifts depending on the lighting: at times leaning towards graphite grey, at others approaching a coal-black hue, and—under intense light—exhibiting a refined, liquid-metal-like sheen.

Powering the watch is the PF070-CSND automatic chronograph movement. It features a high-frequency specification of 5 Hz, equivalent to 36,000 vibrations per hour. The primary advantages of this high frequency are superior timing precision and a smoother sweep of the seconds hand. Few high-end chronograph movements today maintain a 5 Hz frequency, as higher frequencies entail more complex escapement regulation, increased energy consumption, and higher manufacturing costs.
