This is a correct statement. Adrian at VTA has a metal gear replacement if you can find someone to install it. They run about $37.75 US. I too am looking for a quickset rocker for a 5626 I will be working on and saw those rockers on ebay posted above. Insane price for one though. Probably more than the watch is worth. I am going to give the repair a go and see how I get along with installing one of these gears.I believe Adrian did mention he was looking at making this part. I haven't heard any more though.
5606's can be had fairly cheaply on yahoo.jp if you're patient, but there's no guarantees that this part won't be broken. I have a junk 5606 I bought to steal the bracelet off and the quickset doesn't work.
