Officine Panerai P.5000

The P.5000 is a 15¾ ligne hand-wound movement with an exceptional 8-day power reserve achieved through two spring barrels with toothed rims coupled in series, enabling longer, thinner springs. Features a vintage-style design with main plate and bridges concealing most components, reminiscent of old pocket watch movements. The variable inertia balance uses timing screws rather than curb pins. Balance bridge fixed by two screws with threaded rings for endshake adjustment, aiding shock resistance. Used in 'Base' models without small seconds.
