weishi

[gary17]

hey

i have just started using the weishi and im struggling on a read out on a old everite watch.

The pics below show consecutive screens.

I am presuming its beyond help unless someone know something i am missing.

I have moved the adjustment timer on the balance and it does not seem to make a difference.

cheers

The instrument is doing his job correctly, telling you this piece at the minimum needs a complete, accurate service.

Lots of dirt on pivots, teeth, hairspring? Possibly, worn pivots and jewels. Tired, gummed-up mainspring? Basically, no way to be sure without disassembly, cleaning and close inspection.

You are not the only one struggling to interprit tg graphes.

Poor amplitude, fluctuating daily rate, it is not running happy.

Hi Gary I am afraid there is no point putting a duff watch on the machine when trying to understand it. Out a watch on that you know its characteristics and that it is a good one that way you know the machine works and you know what you are looking at. So once having acertained how it works and able to analyse its out put then introduce a watch like the everite and analyse its out put according to the instructions. Its a new toy and will take a little time to understand.

poor amplitude, running slowly, time for clean lube and adjust.at least you have decent beat error

Well you have a range of -102 to +3 seconds/day and I would say that the 'adjustment timer' (more correct term is regulator) is working fine.

If you're expecting a nice clean trace, that will only come with a strip-down, inspection and assembly with correct oil in correct amounts. There are no shortcuts.

Hi Gary  attached is a pdf on gruen calibers and dates.

Gruen Movement Catalog - Caliber Date Table V1.1 (1).pdf

Assuming that the watch is nearly fully wound and you've set the lift angle correctly for this movement then the amplitude is woeful

There is a good discussion here on the topic of amplitude https://omegaforums.net/threads/amplitude-debate.78234/

With the amplitude in the 150 range, everything else is meaningless.

Worth to remind that even without bothering to set lift angle, or having a "large" discrepancy of 5°, the amplitude value is not greatly affected and will be accurate enough for making a go/no to call.

Hi Having searched round all the lift angle providers  It seems Gruen do not provide a lift angle setting, . If anyone knows of a source of lift angles apertaining to the GRUEN watches can you please post it.

Besides the obvious lack of amplitude, I think an important thing to check is to see if stud is loose in stud carrier. Other things to look out for are loose index pin and boot, index, harispring either at collet or stud end, shock assemblies, as well as condition of the pivots.

I'd think anything loose there would show an irregular beat error (spacing between the lines).  That really looks like the good part here.

I have seen similar results once when I had forgotten to tighten the stud screw. But perhaps more likely cause would be bent balance pivot, which produced the ame kind of results on another occasion.
