National Ebauch Cal.?

Description

Generally, quartz movement are not parts of the movement archive, except, they represent something special. Such a movement is unmarked hybrid movement from the Hong Kong National Ebauch Ltd shown here. It’s speciality is the very elegant integrated digital display and the fact, that a german PUW 900 is integrated here.

The plastic base plate is typical for mass produced quartz movements. Only the tiny display at 3 o’clock with its two pairs of connectors are notable.

The analog part of this movement offers a real surprise, since here the mechanics of the german PUW 900 were used and it seems, that its electronics were not used, but the stepper coil is driven by the large far-east electronics module.

Many functions are offered: Besides the three analog hands for time display, the digital window at 3 o’clock offers the whole range of functions, a digital quarz watch can offer: Second time zone, calendar, alarm and stop watch. The latter has only got a resolution of one second.

The display is aesthetically perfectly integrated into the dial as a larger window at 3 o’clock. This is better than any other hybrid movement!

On the open dial side, you can spot the connectors for the LC display and the coil at 7 o’clock, which drives the piezo loudspeaker in the case back.

The closed dial side is not noteworthy at all. Any cheap quarz movement looks more or less the same.

Nevertheless, the movement shown here is a collectors item, since it is the most elegant execution of a hybrid analog-digital movement, and far east electronics meet german mechanics.
