The french Parrenin 66 (stamped as “CHP 66”), which the german manufacturer Emes used as “Emes 18a” after assembling the movement, which they obtained in parts, inhouse, is a 10 1⁄2 ligne pin lever movement with a balance bridge. It was released around 1970.
Emes used it for example in the mini alarm clock “Emes sonochron”, which got notoriety for being used at bomb attacks.
The stamped base plate with its contemporary plastic winding system frame shows, that it’s not a top movement. It’s a cheap pillar construction, where all bearings (except for the balance wheel) are free from rubies, but only made of brass.
Unlike the Parrenin 660 the crown wheel is only riveted not screwed.
The gear train is familiar für a pin lever movement with directly driven center minute and subseconds (which are not used in every version) as 6 o’clock.
The shock protected anular balance (here in RUFA-Anti-Shock bearings) still beats slowly with 18000 A/h. It controls a pin lever movement with top down lever, which means, that the lever is above the escapement wheel and its pins point downwards to the base plate.
The anular balance resides unter a bridge, this is an unusual detail.
On the dial side you see the yoke winding system, whose clutch lever works also as setting lever spring and is additionaly the cover for the pointer and change wheel. A maximum efficiently construction!
