Hello. Watchmaker here. it is indeed "plastic", but the "heart" itself is a Nivachron hairspring that basically co-developed with swatch group and APRP, with that it made the watch anti-magnetic, and pallet fork with the escape wheel made out of the composite, it virtually create less friction and less impact. And also those C07 movements are highly serviceable, so it's not just throwaway movement, they use special lubricant compared to the common swiss lever 9415 oil which if other watchmaker out there have the proper lubricant they could fix this watch too, and also the rate is adjustable by adjusting the eccentric screw as it's a free sprung balance like those in higher end watches like Patek philippe, Vacheron constantin, omega, rolex, AP, etc. They exchange the movement so the turn around time of servicing is faster while the old movement sent to Swiss to service as we're not only servicing Tissot in the workshop but also up all the way to Breguet which need much more time to spend with.
