I've owned both and thus far the 2824's have been more accurate but this may be due to the fact that even the lowest grade is regulated to 2 positions whereas I'm not sure the SW200 has any regulation, but I may be wrong on this.
So, I'll vote 2824 but I love them both!
Hard truth is that with a little R&D, Japan could easily produce mechanical or auto-mechanical movements on par with almost any mid-priced Swiss movements
Invicta's implementation of the Seleta movement has been spotty. I have had several issues with them as well. The ones that run, run well. I can't say if this is Invicta's problem, or a problem with the movements themselves. I won't sell any of my Invicta's with the SW200 because I don't want to 'stick' anyone with a bum watch. One of mine had the date wheel advance only half way, this after many weeks of running fine. Several have had crown issues, including the crown/stem pulling right out of the watch.i owned 3 invictas with the sw200, 2 of these were defective, so i sold the good one, a month later my friend told me that the watch have stopped!
