Uwersi 57/8 (SCI CLD)

Description

The Uwersi 578 was available in different versions, with and without indirect driven center second and with or without date indication (which was advertized on the case back with using three patents, but consists in fact only of a gear and a spring). The movement described here contained everything.

The flat nickel balance, without screw, long regulator arm and shock protection, regulates a conventional pin lever movement. However, there’s one speciality with the pin anchor: The pins don’t consist of metal, as usual, but of synthetic rubis. Technically, this is only a minor improvement, but it helps using two more advertizing-effective jewels. And these two are not the only additional jewels in this movement: All the gears are not only beared in jewels, but they all have cap jewels, too, even if there’s a gap of a millimeter beween the two jewels. The second hand axle is even beared in two jewels, since it runs in the minute train, which is beared, and has got an additional jewel put losely on it. The only position, where a jewel bearing would have been really useful, at the spring, which keeps the indirect second hand gear in position, is of course un-jewelled…

On the dial side, you see a familiar picture: A simple rocking bar winding mechanism, a very simple click spring mechanism with just a spring and the advertized calendar mechanism, which only advances slowly and cannot be corrected quickly. This mechanism of three patents consists only of one gear with a pin. It drives the small date disc with the tiny date numbers.
