The Bettlach caliber EB 8350-67 is a mid-size ladies' watch pin-lever movement.
As most of the EB movements, this movement also has got some constructive specialities:
The most noticeable thing is the moveable hairspring stud, which is made of an U-shaped piece
of metal, which is inserted into the balance cock. This way, it can be easily moved.
The 8350-67 also uses a yoke winding system, which is located in the inside of the movement and
hardly visible at all.
Like all EB movements, this one uses a pin lever, too. Here, the lever axle is beared in two
cap jewels to achieve the important number of seventeen jewels. The minute wheel is located
decentrally to allow larger diameters of the balance and mainspring. The hands are driven
indirectly by the mainspring on the dial side.
