4:55 - The most amazing tests for this watch model were probably the acceleration test to 7.25 G x 5 minutes and then to 16 G for 30 sec, and the shock resistance test of six 40 G shocks in 6 directions. These watches were built probably stronger than most tanks.
Loved this video! I have a vintage 1976 Speedmaster Pro "moonwatch" as well as a few modern ones (one standard as used by NASA for EVA, one with sapphire display caseback, and finally a Limited Edition with panda dial).
