Having a design flaw in first generation movements is not unexpected. The Oris Calibre 400 had an issue with time setting. I knew I was taking a risk buying a brand-new movement. The A26 clearly had something with the automatic winding. I don't know if the A26's shipping now have been cured or not. I know that the Oris Calibre 400 was stealth updated to fix the issue. Unfortunately, manufacturers don't typically release press releases saying what they've fixed, because they don't want to call attention to the fact that there ever was a problem.
All in all, I still think the A26 is an upgrade over a 2824, they just need to fix the design flaw. The time keeping and positional variance was immaculate. I'm going to ask my watchmaker if the new replacement parts have been modified from the original design or not, and maybe that will have the answer to the question for us.
