Helvetia 64

Description

Among the most beautiful movements, Dugena used in the 1950ies, ist the Helvetia 64, which Dugena rebranded as their caliber “Dugena 596”.

With a diameter of 13 lignes, it is a very large manual wind movement in golden colors.

base plate

base plate

The base plate (which is unfortunately heavily used on the the specimen shown here) tells us, that all important bearings contain rubies. Since the center minute wheel is not ruby-beared, you can assume, that the escapement wheel bearing contains a cap jewel on the movement side.

gear train

The Helvetia 64 uses the classical gear train with directly driven center minute wheel, followed by third wheel, seconds wheel (at 6 o’clock) and steel escapement wheel. The latter has got a KIF Duofix cap jewel on the movement side bearing.

Due to the large diameter of the movement, the gears are also rather large, but still a part of the available space is unused.

The large golden toned Glucydur screw balance beats slowly with 18000 A/h and is beared in two Incabloc shock protection bearings. It regulates a classical swiss pallet lever movement.

On the dial side, you see the large setting lever spring of the yoke winding system, and also the Incabloc shock protection, which seems to be pretty small, compared with the large diameter of the main plate.

The main place has got bevelled angles to save a little height.
