32xx movement problem poll and data thread

32xx amplitudes of 300 degrees?

I think we do NOT see 32xx amplitude values of 300 degrees because these movements are regulated to fall into -2/+2 sec/day regime, which corresponds to the 5-position average rate 'X'.

With the specific 32xx isochronism behavior, as described in my post #3647 (page 122), one would need to go to higher X rate values to measure higher amplitudes in horizontal and vertical positions.

I have seen exactly this effect for my 3235 watch, which was regulated by Rolex from X = +4 s/d to X = +1 s/d.

After regulation all high amplitudes had decreased by about 10 degrees, which should not be the case for 'good' isochronism.

I propose an interesting experiment to Bas and/or all other RSC watchmakers:

Step 1: Take a serviced 32xx movement, regulate it X = +5 s/d (or a bit higher) and measure rates, beat errors, and amplitudes with your timegrapher.

I expect that amplitudes will be above 290 degrees (DU, DD) and above 250 degrees (9U, 6U, 3U).

Step 2: Regulate the same caliber to X = +1 s/d and compare the differences.

I expect that all amplitudes will be lower.
