Uwersi 47/11 CLD

Description

In the 1950s, at times of the german “Wirtschaftswunder”, people wanted to show their possessions. And what is more impressive than a golden watch with additional functions like a chronograph or an additional hand for a calendar.

The Usersi 47/11, distictable by the straight edges on the short side, was a rather simple windup form movement with an analogie date indication, but at least with a pallet lever escapement.

All important bearings of this cheap pillar construction are equipped with synthetic rubies. To achieve the advertizable number of 17 jewels, the movement side (and so, visible) minute wheel bearing has got a bearing ruby, and the visible escape wheel bearing a cap jewel.

The gear train is pretty simple: The mainspring barrel drives the center minute wheel, followed by third wheel, seconds wheel (for a decentral seconds indication at 6 o’clock) and finally the steel escape wheel.

The Uwersi 47/11 cheats on the visible bridges, which look, like if they were two individual ones, one for the gear train and one for the mainspring barrel. In fact, there’s only one single bridge for everything, into which a partial slot is milled in.

This movement builds pretty high, typical for a pillar construction.

As regulating organ, a screw balance is used, which is beared in two shock protecting bearings, which could not be identified further. On the specimen shown here, the one on the balance wheel cock is even missing.

The balance wheel beats with 18000 A/h and can be regulated with a long regulator arm plus scale.

On the dial side, you see the rocking bar winding system and the simple ratchet, which consists only of a spring, which blocks the ratchet wheel.

At 9 o’clock there’s the date switching wheel with its pin, which is driven by the hour wheel. Once per day, it engages with the center date wheel and advances it one step. There’s no quickset possibility.
