The 1000 and 1010 series were made to a budget certainly, and also were made to be very thin. Thin movements come with built in compromises, and these are apparent on the dial side of this movement. I've seen plenty with problems, mostly related to the cannon pinion arrangement (which is a bit unusual) and these parts can be damaged if that particular assembly is not handled right during servicing.
On the plus side, they tend to be very accurate. I certainly see far more of the 550 based watches than I do these, but for the most part they don't present any insurmountable issues with servicing. The 550 based watches are the last movements that Omega has all the spare parts available for, so anything earlier than these you may have to rely on the open market for parts. The 1000 and 1010 series are pretty much fully supported.
