Description
The Baumgartner (BFG) caliber 911 is modern built ladies' watch movement, which contains
a sophisticated date indication mechanism.
Its balance is secured in two KIF Protechoc systems and contains a finger for the escapement.
The escapement anchor in located in one jewel on the movement side; on the dial side, there's just
a metal bearing. On this way, the unusual number of five jewels is achieved.
The center second is driven directly; the minute wheel is located de-centrally, which
allows a flatter
construction and larger diameters for balance and mainspring. The hands are driven on the dial side
by the mainspring.
The winding mechanism is a yoke winding mechanism, which is normally a feature of "better" movements,
but the BFG 911 is in fact a "better" pin lever movement, too, which sometime even reminds of a
anchor movement.

The date mechanism is unusually complicated, with gears, that contains teeth's in different
lengths, with springs and moveable jumpers. Because of this, the date switches semi-fast
in only 45 minutes and can be corrected semi-fast, too, by turning back to 10:30pm.
