Question: is the omega speedmaster automatic?
Answer: The movement of the Speedmaster Professional is, of course, the hand-wound Lemania based chronograph, either caliber 321, 861/863, 1861/1863, or 3861 (depends on the age of the watch). The Speedy Reduced has an automatic movement, based on the ETA 2890-A2 (no date), also known as Omega caliber 3220.
