I don't think it's the 7750 though. From what I've read, it's a lower grade chrono movement specially made for Tissot.
Also, Tissot is using the 7750 for their new "Couturier" range of watches which is at a higher price range.
You have seen watches with the eta 7750 for RM2k-RM3k price range? Do tell me more.
The lowest price of a new watch using the eta 7750 (in Malaysia anyway) is Hamilton (maestro, jazzmaster) which is approx RM4k. Even the Archimede and Steinhart chrono are at least EUR800 (RM4k).
