Patek Philippe 30-255 PS
High confidenceThe twin barrels give roughly 65 hours against the 215's much shorter reserve, which is the practical distinction and is measurable without opening the watch. Worth noting because the two calibers sit in visually similar Calatrava cases and the reference is the only other thing separating them.
