Felsa 302


The Felsa 320 is one of the typical larger sized ladies' watch form movements, which were made in the 1940ies.

During its production time, it was available in a few versions, which were all functionally the same, but differed in their execution.

As the base place shows, all important bearings contain synthethic rubies. Together with the other functional rubies, their total number is 15, which was the optimal number at that time. More jewels were pretty uncommon.

The tonneau shaped construction allowed the use of a large mainspring barrel and a large balance, while the gear train was very small and stocky.

The gear train construction was typical of that time: The mainspring barrel drives the center minute wheel, followed by the third wheel with a small and the second wheel with an even smaller diameter. Finally, there’s the compareably large steel escape wheel.

To free more space for the escape wheel, it runs partially below the second wheel bearing.

The two-leg screw balance is not shock protected, of sure. It beats with 18000 A/h, whose exact frequency can be adjusted with a long regulator arm and scale on the balance cock.

The Felsa 302 uses a swiss pallet lever escapement with transparent pallets. No other manufacturer used transparent pallets so often as Felsa did.

During its construction time, the dial side was also reworked a bit, which you can see on the more or less large cutting on the mainspring barrel.

Of course, this movement has got a yoke winding system, and as usual, a partial minute dial was engraved, a tool for adjusting the movements outside the case and without dial.
