65h power reserve
The 30-255 PS is a hand-wound movement manufactured by Patek Philippe. It achieves a 65-hour power reserve through two mainspring barrels arranged in parallel, a design that contributes to its compact construction of 164 parts. This is a base caliber in Patek Philippe's lineup, used in simpler timepiece references.
