Parmigiani Fleurier is a Swiss luxury watch brand that is known for its high-quality craftsmanship and unique designs. The Parmigiani Tonda Flyback Chronograph is a watch that contains a specific type of movement known as the PF354 caliber.

The PF354 caliber is a self-winding mechanical movement that contains 51 jewels and operates at a frequency of 28，800 vibrations per hour. This high frequency ensures exceptional precision in timekeeping. The movement also features two barrels， which means the watch has a power reserve of up to 50 hours.

The most notable characteristic of the Parmigiani Tonda Flyback Chronograph is its flyback function. This enables the wearer to quickly reset the chronograph by pressing a single button， without first stopping the timer. This feature is particularly useful for timing events that take place over short periods of time.

In addition to the flyback function， the PF354 movement also features a split-seconds chronograph. This allows for the measurement of two separate time intervals simultaneously. The watch also has small seconds and date displays， all of which are conveniently located on the dial.

Overall， the PF354 movement is a sophisticated and complex mechanism that reflects the high standards of craftsmanship and quality for which Parmigiani Fleurier is known. Its precision， reliability， and functionality make the Parmigiani Tonda Flyback Chronograph a highly sought-after timepiece for collectors and enthusiasts alike.
