plastic bits........ ???
5606 - the movement that doesn't last
out of the many 5606's that I have handled or owned at one time or another, I have yet to see a one that has the quick set working.
what the heck is wrong with these movements?

Maybe you could persuade Randall to make more of the metal ones...they would outlast even the newest 7s series movement
I've got 3 of these movements on my bench at present, they are a heartbreaking movement. All 3 are highly accurate and have great amplitudes, but don't quick set. I've got a corrector rocker staked on my bench at present while I try and think of a "ghetto" method of repairing the plastic star wheel. Apparently even NOS parts still have a cracked plastic star wheel. I'm leaning towards knocking out the pin, joining the wheel with some construction grade epoxy then using a smoothing broach on the inside of the wheel which bears on the pin. If this doesnt work, the other option is joining the wheel to the gear underneath and avoiding quicksetting anytime near the day/date change over time.
The part in question looks like this, apologies for not being more detailed, I need to grab one of those nifty USB microscopes -

Both the 5606, 5626 (and as far as I know also the 5646) use exactly the same corrector wheel rocker part (981560).Time said:
I have a couple of 5606s that work just fine, and a couple of 5606s with broken quicksets.
In my honest opinion, the explaination that it is the degradation of the material alone does not hold true.
It may well be that the plastic wheel becomes a little brittle over time. But I personally think what eventually finishes them off in most cases is ONE careless use of the quickset function when it should not be used.
In fact, one of the honored members here bought a 56 Chronometer. The previous owner reported that the Q/S worked just fine - until he lend the watch to his girlfriend

well, that would do it. :57:
seriously though, how many 5626 do you have with non working quick sets?
If compared to the 5606, the number of failures in my experience is exponentially larger on this movement.
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...

I have my share of 56 watches.
The GS and KS ones nearly all works fine, even the very well used ones, but the majority of the 5606 have this problem.
Sadly as the Lordmatics are nice watches in so many ways.
But the best are the 5621, completely faultless :57:

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
