There was a Taiwanese version called "Taike Boy" (泰可BOY) but I dunno if that was the original or not, it might have been another licensed variant.
The original designers seem to have been based in Hong Kong but Watara (or "Watary" sometimes) and Magnum and Bon Treasure were all ultimately owned by the Malaysian company
Magnum Corporation & I think it was probably intended as an export product from the start so maybe it never really had an "original" Chinese name.
(although one thing I think is weird is the back label on the Supervision is almost identical to the one on the Gamate)
