Aqua Terra requires 2 barrels to achieve 70 hour power reserve. The MT5612 does 70 hour power reserve with 1 barrel, if I'm not mistaken. The MT5612 also has a free sprung balance wheel.
I will say the Omega has better finishing due to rhodium plating and cotes de geneve, but since I can't see the movement to me it doesn't matter much. I believe both movements are COSC certified and have silicon hairsprings, but the MT5612 has been frequently reporting accuracy of under 1 second a day, which is insane for an automatic movement. The winding of the MT5612 is BUTTER - it's honestly so smooth I didn't even realize I was winding the movement.
Great info. And I would agree there. Def a watch I need to try out In person to appreciate
