That is obviously a bit trickier than simply moving a single screw on a balance bridge in a controlled watch, so these need more effort to acquire precise, but with sufficient ability and time, they are inclined to be stable, both in the long and short term, compared to regulated movements. Be aware that, like Rolex, Omega puts its screws onto the interior of the balance wheel instead of the outside. This allows them to use a larger balance wheel without making the movement bigger. Compare this strategy into the more complicated, but no longer powerful, ones from Breguet and Tudor.Another special component to the 8500 and to this 8601 is the silicon hairspring. Omega did not devise the silicon hairspring but they’re the first company to produce them at any meaningful scale. The benefits to the silicon hairspring are mainly that it is completely immune to magnetism and that it’s much lighter than metallic alloys, meaning it is less vulnerable to losses of precision due to vibration. I have no idea what functionality benefits, if any, this provides over competing options, but it is unique nonetheless.The lovely matching rotor is mounted on ceramic ball bearings, which can be more durable than metallic ones. The 8601 is a portion of a diminishing minority of watchmakers which are sticking together with bidirectional automatic winding, meaning that this movement automatically winds in both the clockwise and counterclockwise directions. While unidirectional winding works good, and can be used by many respected brands, I prefer bidirectional because it’s generally quieter and you will almost never feel that the rotor moving in your wrist.
