This version of the Tonda PF speaks to the growing demand for smaller sizes and the "vintage" flavor they evoke. In this form, we get a rare look at what an integrated steel watch might have looked like from the Parmigiani Fluerier brand if it had produced watches during the segment's heyday in the early 70s.

A detailed case profile is forged from steel and platinum with its distinctive Tonda teardrop lugs and knurled bezel; the Tonda PF Automatic 36mm is unmistakably Parmigiani Fleurier from every angle. The curvature of the case compliments the wrist's natural shape and drapes like a well-made suit in a very ergonomic fashion.

Housed in the Tonda PF Automatic 36mm is an all-new automatic movement made especially for this reference. Measuring 25.6mm x 3.9mm (just 0.9mm thicker than the micro-rotor PF703), this 179-part in-house caliber beats at 28,800vph (4Hz) and bears a power reserve of 60 hours. Instead of an off-center micro-rotor, the PF770 relies on a central 22k gold skeletonized rotor, which is shared in the other automatic Tonda PFs in the collection. The sapphire case back reveals the Côtes de Genève finishings on the bridges, the beveled edges, and the polished and sandblasted areas of the skeletonized gold rotor.
