I'm a psychologist who started repairing vintage Rolex watches as a side hustle. Now watchmaking is my main gig.
Briefly

Greg Petronzi, originally a psychologist and professor, turned a lifelong passion for watches into a major career shift toward watchmaking. Initially attracted to their mechanics during middle school, he pursued an education in psychology, culminating in a doctoral degree. However, following an informal apprenticeship under experienced watchmaker Rik Dietel, Petronzi honed his skills in repairing vintage Rolex watches. As his expertise grew, he shifted watchmaking from a hobby to his primary occupation, ultimately finding it more financially rewarding than his psychology work, marking a significant career evolution.
"Petronzi, a psychologist and professor, found his passion for watchmaking blossoming from a hobby into a lucrative enterprise, ultimately out-earning his psychology profession."
"After a long journey through psychology, Greg discovered a latent talent for watchmaking, transforming his casual interest into a successful career through self-teaching and mentorship."
