Parmigiani Fleurier PF337

The Parmigiani Fleurier PF337 is an automatic movement with hand-winding capability, featuring a dual time zone complication that allows independent adjustment of a second timezone to the minute. It contains 316 components and incorporates Côte de Genève finishing with beveled bridges. A notable feature is its dual series-mounted barrel configuration, which improves isochronism and rate regularity, delivering a 50-hour power reserve. The caliber was introduced in the Toric Hémisphères Rétrograde and was a world first for providing minute-accurate dual time displays.
