Movement parts made of plastic!

[BlueHarp]

I've just got a very strange Q&Q watch. The movement (Q&Q 2604) has several parts in ... plastic! I know this is the case in other watches, such as Seiko 5, but that caliber has an escapement wheel, a lever and a balance finger made of red plastic. That's incredible!

The funny thing is that is works quite well. I disassembled partly the movement because it didn't work, and then reassembled it (6 pivots under the same bridge ...) and it's ok.

I guess this watch won't work well for a long time, but this is an automatic watch which indicates the hour, minutes, seconds, date and day, and it was very cheap when produced.

As I understand, Q&Q belongs to Citizen.

Has anyone had the opportunity to see such a "plastic caliber"? Here are the details of that movement :

I was not familiar with this particular plastic watch but I was familiar with the ones at the links below. Then plastic escapement's Swatch group is doing that with one of their watches currently is don't remember which number it is. To certain degree it doesn't matter there's no parts available for its but it's just the escapement that's plastic everything else is metal

Thank you for the feedback. I didn't know that Tissot produced such kind of movements. As for my Q&Q wach, everything was ok for the first hours, but it's losing time now. I guess the self-winding system isn't as efficient as it should be, although the rotor moves freely.
