Fact is that the Weishi 1900 can have a better accuracy of +/- 0.1 s/d compared to the Weishi 1000 with +/- 1 s/d.
I am not going to argue with anybody here what matters or is needed.

Ohhh, Dr. Ego is extra crabby today! I love how in the process of arguing with somebody you assert that you are not going to argue with anybody. Well done!

The Weishi 1900 is a seriously good machine for dealing with the sort of figures we are talking about ion this thread which is mainly about the 32xx movements and their problems.
I, personally had a Weishi 1000 to start off, That was exchanged for a model 1900 within 2 days as I found the data I was collecting was nowhere near accurate enough for serious recording of data and adding to graphs etc.
The 1900 model fulfilled what was needed.

Both the 1000 and the 1900 measure amplitude to the same 1.0 degree resolution, right? The 1000 does s/d to 1.0 sec and the 1900 does s/d to 0.1 seconds. You are saying you can't tell if there is a problem based on 1 degree and 1 second resolution? If the 1000 tells you the amplitude is 195 degrees and the timing is -25 s/d, you aren't really sure if something is going on unless you know that it is really -25.2 s/d?
I would assert the only value of 0.1 s/d resolution is when trying to regulat to "perfection." I.e. in situations where 0.3 s/d isn't good enough, and you want to target exactly 0.0 s/d. But a) we aren't working on our watches and b) the 32xx issues don't manifest themselves in such small ways. When there is a problem, there is a big problem, and 1 s/d is going to be plenty to spot it.
Again, I never argued that the 1900 isn't a superior machine. But for OUR PURPOSES HERE, i.e. detecting a problem, I still say there is no meaningful difference. Obviously the Witschi class of machine gets you something entirely different. But 1900 vs 1000? Just not seeing it, sorry. To say owning the 1000 is a "pity" is just more condescending crap that is unhelpful and rude (but on-brand).
