plastic bits........ ???
Time said:the 7S series have plastic bits, but I don't see this problem.
iButrusCor said:Only time will tell as the part that fails on the 5606 is also plastic on the 7s .
Both the 5606, 5626 (and as far as I know also the 5646) use exactly the same corrector wheel rocker part (981560).Time said:you know what. There are other movements of the same era that use plastics and don't have this problem.
the 5626 is one of the many.
I really think Seiko just made a mistake in the design of the 5606

The 562x has a metal quick set star, as far as I'm aware, hence not prone to failure.StartSomething said:Well, I only have one 5625 - and the QS works
What I intended to say though is that I do not see ANY technical reason for the higher defect rate of the 5606s.
I would speculate that the LMs - being a lot cheaper than the KSs, even more so today than in the 60s and 70s - have seen much more use and abuse than their KS counterparts...
As I wrote earlier, they do not.haloeight said:The 562x has a metal quick set star, as far as I'm aware, hence not prone to failure.
Thanks for looking into this further Hermann. It's good we've finally solved this mystery!StartSomething said:Many thanks for Noah. R. for helping me out with the 5645A and 5646A calibre parts lists!
So this finally confirms it and puts a myth to an end:
The 56GS movements DO NOT USE A METAL QS COMPONENT, it also uses the plastic corrector wheel (part# 981560).
The QS parts are thus the same on both the 560x, 562x and 564x movements with calendar.
Been looked into before and done, albeit at a high cost. It's not a complex part but would be a lot of work to machine/make yourself.chris141058 said:I have at least 5 x 5606 LMs with broken day/date quick set.
Would replacing the weak plastic part with a metal one solve the problem (if it were available). If so could we try to get someone interested in producing them? It sound like on this forum alone there would be a high demand.
