Parmigiani Tonda PF Gregorian Annual Calendar PFC907-1020001-100182

The Parmigiani Fleurier Tonda PF Gregorian Annual Calendar Ref. PFC907-1020001-100182 is a standout example of modern haute horlogerie that marries refined aesthetics with genuinely impressive mechanical sophistication. Housed in a 42 mm stainless steel case with a hand-knurled 950 platinum bezel, the watch wears with an elegant presence thanks to its polished and satin-finished surfaces and integrated steel bracelet. Its warm-grey Grain d’Orge hand-guilloché dial is both subtle and richly textured, and is balanced with rhodium-plated appliqué indices and delta-shaped hands for crisp readability.

What truly sets this timepiece apart is its in-house calibre PF339, a self-winding movement that delivers a retrograde annual calendar (date, day, and month) alongside a precision moonphase display that requires adjustment only once every 122 years in both hemispheres—an impressive feat of astronomical accuracy. The annual calendar mechanism automatically accounts for the differing lengths of each month and only needs manual correction at the end of February in a leap year, adding genuine practicality to an already elegant layout. With a ~50-hour power reserve, sapphire caseback, and 100 m water resistance, the Tonda PF Gregorian Annual Calendar is a superb blend of technical depth, design purity, and everyday wearability—a refined choice for enthusiasts who appreciate nuanced complications executed with discreet luxury.
