That's a tough one, though I think it would count as having two quartz-regulated balances, one directly driven and another indirectly, so it would still be a quartz.

That is of course if the coil-driven balance can overpower the mechanical one. Mechanical movements have way more torque than electronic balance ones. That is why for instance Cosmotrons don't need that many jewels, there's just not that much torque.
