Uwersi 57/8 (SCI CLD pin lever)

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. 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. A curiousity is, that below the balance, there’s a blind jewel without any function at all.

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.

These better pin-lever movements were quite popular in the early fifties, when nobody had enough money for a “good” watch, and last but not least, its unusual details make it a collecting-worth movement.
