Guys, unless you are planning to replace your SH3135 with a gen, you may be interested in reading this post on RG. Obviously not all rep movements are bad but IMO the "super clones" have a lot of room for improvement yet. I'm sticking with 2824/36 and Miyotas for now.

This article is all about aesthetics. Decent point about the potential for chipping paint to jam up the works, but notice how few people have written in with problems from this, or other shortcomings with the clone movements in the past couple years? Don't forget, people tend to run to the forums with problems and stay quiet about things just carrying on as they should, so the scarcity of recent bad feedback on even the SA3135, let alone the superior SH3135, is good evidence that there's no reason to stay away.
Ultimately the whole point here is to have fun, so always go with the movement you will enjoy more. But if you'd be inclined to a clone movement for the more gen-like crown position, potential to use gen hands, dial, etc., don't let reliability concerns hold you back.
