The speciality of the AS 962 is the giant (compared to the rest of the movement) mainspring barrel. It seems to be pretty rate, and also its shape, with a length almost twice as long as its width, is a but unusual.
Almost all bearings, except those of the center minute wheel and the mainspring barrel, are equipped with synthetic rubies. This was pretty standard that time.
The odd shape also results in a decentral seconds indication pretty near the center of the movement.
Besides that, the gear train consumes fre space, but is construction-wise absolut standard with directly driven center minute wheel, third wheel, decentral seconds wheel and steel escape wheel.
The screw balance is not yet beared in shock protections. It regulates a conventional swiss pallet lever movement, and its beating frequency of 18000 A/h can be regulated with a long regulator arm and scale.
Much place on the dial side, that’s almost all, which can be said about the AS 962.
Of course, as usual on AS movement, it uses a yoke winding system. The setting lever spring is quite large, however.
Near the lower left corner, you can see the balance wheel bearing, which only consists of a bearing- and a cap jewel. This was also standard these days.
