Authentication Notes
Movement
The retrograde minute must fly back, not reset gradually
A retrograde hand travels along an arc and returns to its start instantaneously at the end of its travel. Wait for the hour: the minute indication should snap back. A hand that travels backwards gradually, or that simply continues round, is not driven by a retrograde mechanism. Combined with the satellite indexing, this gives two independent functional tests on one watch.
Movement
The winding-efficiency indicator responds to how the watch is worn
The indicator reports the energy the automatic system has actually delivered over a recent interval, so it CHANGES with activity — it should read differently after an active period than after the watch has been still. A static indicator is a printed or non-functional imitation. This takes hours rather than seconds to check, and it is conclusive.
