Writer Zach Blass spotted wearing a Parmigiani

Spotted enjoying what appears to be a warm afternoon in an urban setting, watch journalist and editor Zach Blass — known for his work covering horology across major watch media outlets — was photographed wearing the Parmigiani Fleurier Tonda PF Micro-Rotor in rose gold. For someone who spends considerable time evaluating timepieces professionally, the choice speaks volumes: this is not a watch worn for spectacle, but for conviction.

The Tonda PF Micro-Rotor, launched as part of Parmigiani's 2021 collection overhaul under creative director Davide Lombardini, represents a genuine reset for the Geneva-Fleurier manufacture. The 40mm rose gold case features an integrated bracelet with a distinctly architectural profile — tapered lugs flowing into a five-link bracelet — that draws clear parallel to icons like the Royal Oak and Nautilus while establishing its own geometric language. The dark slate dial visible here shows applied baton indices in rose gold and a discreet date aperture at 3 o'clock, all finished with extraordinary surface discipline.

At the heart of the watch beats the PF601 calibre, a manually wound micro-rotor movement measuring just 2.6mm in total height. Parmigiani builds its own movements, springs, escapements, and cases in-house through its Sandoz Family Foundation-backed network of ateliers — a level of vertical integration matched by almost no other independent. The micro-rotor configuration allows the movement architecture to remain visible and thin without the visual interruption of a full-sized rotor.

For collectors, the Tonda PF occupies a compelling position: legitimate manufacture credentials, architectural design coherence, and relative scarcity compared to the Swiss giants dominating the integrated-bracelet conversation. Blass, as a working watch journalist, would be acutely aware of this positioning — wearing the Tonda PF is an informed statement, not a default luxury purchase.

At retail the rose gold Tonda PF Micro-Rotor sits at approximately $38,500 USD. On the secondary market, demand has remained steady as collectors increasingly recognise Parmigiani's technical pedigree, with grey market prices tracking close to retail — a sign of healthy, non-speculative desirability.
