The caliber mark seen here is ST 1686. At this time Standard Time (ST) was owned by A Schild (AS) and these movements can be found with either the ST 1868 or AS 1686 caliber marks.
Protecting the balance pivots from damage by shock is an Incabloc mechanism. A similar shock protection mechanism is used on the dial side of the movement.
