Audemars Piguet 7121

High confidence

The end of the 920 lineage in the Jumbo after fifty years. The practical distinction from the 2121 is the power reserve — roughly 55 hours against the 2121's roughly 40 — which is measurable without opening the watch and is the cleanest way to separate a 16202 from a 15202 if the dial text is in doubt.
