In the 1980s, when quartz watches were affordable for almost everyone, it was quite impossible to sell mechanical watches any more. The anything, than only by the price. Since a good mechanical movement couldn’t be produced that cheap, it was neccessiary to construct a movement the same way like a cheap quarz movement, with simple and cheapest parts, with a lot of plastic and assembled by robots. In case of an error, it should’t be repairable, but disposed and replaced by a new movement.
The Q&Q 2670 is the base caliber of a series of ultra cheap mechanical movements, ending with the Q&Q 2604, which has got a selfwinding mechanism and a day-date indication.
The base plate of this 11 1/2 ligne pillar movement is a simple punched plate, onto which the balance assembly is already mounted.
The winding stem is housed in a plastic cage, which also carries the ratchet. This ratchet consists only of a simple spring, which blocks the crown wheel, which is riveted onto the inner side of the mainspring barrel bridge.
The gear train, the lever and the balance, they are all housed under the one and only top movement plate. Happy servicing…
The gear train construction is pretty modern and old-fashioned at the same time: On the dial side, the mainspring barrel has got an additional wheel with a slip clutch, which drives the gear train. This reminds a lot of a Roskopf movement.
The rest of the gear train is really modern with directly driven large driving wheel, third wheel, center seconds wheel and escape wheel.
Escape wheel, lever, ellipse and plateau of the two-leg anular balance are all made of plastic!
The balance wheel is beared in two plastic bearings. The hairspring is at least pinned with the hairspring stud, and not glued, but the hairspring key is a simple bow, through which the hairspring runs. You cannot expect good accurancy from such a simple construction.
Of course, there are no jewels at all in this movement. The read colors of the lever and escape wheel bearings are the red colors of the plastic axles.
As on cheap quartz movements, the wheels on the dial side are mostly made of plastic.
