Collectors target this reference for its tonneau-shaped stainless steel case, which follows the golden ratio proportions established by Michel Parmigiani. It features the in-house Calibre PF331, an automatic movement with a 55-hour power reserve and twin barrels. The dial typically displays a guilloché pattern with a date aperture at 6 o'clock and delta-shaped hands. This model represents the brand’s foundational design language and is noted for its ergonomic teardrop lugs. On the secondary market, the PF000331 generally trades between $4,500 and $7,500 depending on the presence of the original steel bracelet or leather strap. A notable production detail is the movement's high-level finishing, including Côtes de Genève and perlage, which was uncommon for steel sports-luxury watches in its original price bracket.", "score": 203}]}
