My Sub is less then two months old, and I wear it 24-7, but right now, it is 19 seconds slow for the last 13 days, that works to (rough estimate) 1.45 seconds a day slow. Well within standards and I am very happy.

Thanks for your information.
I assume 24-7 means 24 hours 7 days.
Then you have a kind of "permanent" winding.
Your watch will then probably not approach low amplitudes hence your rates will not become strongly negative, that does not surprise me. Can you do some easy “exercises" for example let it rest for 24 hours and see again how it changes. Data with a timegrapher or an App would be great too. Thanks for contributing in a positive way!

I have PM'd lol-x to see if this thread could be stickied for a few weeks just to increase visibility. Regardless of which side of the issue one finds themselves, I think we'd all benefit from a large sample size.

Sure, I can not wear it for 24 hours.

Rest in what position ? Dial up ?

Yes, that's what I do.
My measurement sequence is seen in post #11:
DU (dial up), 6U (six up), 9U (nine up), 12U (twelve up), 3U (three up), DD (dial down).
At the end of this sequence I go to DU position again.
In addition: after full watch winding I place the watch on the timegrapher and wait 15 min to stabilize, then measure starting with DU. After each position change, I wait 3 min before measurement start.
I know very well that Rolex and many watchmakers don't use the 12U position for measurements and data analysis since the 12U watch position on our wrists is very uncommon.

I have only had my 1266010 Sub for a couple of weeks, but it runs 0.0 on the wrist, and can gain a second overnight left dial up, and lose a second overnight left crown up. I'll keep an eye on it for a year and report back.

Agreed

It's going to be the only/best chance of gathering something that resembles conclusive data that exists outside of the mothership

Here it is:
I think yours is probably going to be ok within reason.
Of course we can't gauge how hard it was knocked and by nature, the results of a knock are a lottery.

DJ41, bought August 2019. Worn a lot. Most of the time since then it has been worn. I'd estimate close to 300 days on the wrist. Amplitudes don't drop below 200 after 24h. Timing also doesn't seem to become slow. On the contrary, it seems to be gaining more now than when new.

I'm obviously not an expert; if you wear the watch and the +/- seconds is within specs or what one was hoping for, why does the amplitude matter?

As I've intimated previously.
We have no 32xx movements in our household by choice.
We are not necessarily early adopters by nature.
Besides, our current Rolex watches are running perfectly.

But I've definately come close on two separate occassions with a particular DJ41.

As I've made clear, this thread is great
To answer your question.
No I have no data to offer on this specific topic.
Except to say that it doesn't take into consideration all scenarios which may have a bearing.
But you are aware of that aspect

Sorry, my late Dad was recognised as one of "the legends" of the bureau of statistics.
So I have more than the usual understanding of the construction of polls and sensis gathering questions after much robust discussion with him over it every few years

Carry on and best wishes

So the reason we’re recording amp is because it’s one of the key symptoms of this movement if it affected by the issue a lot of the threads are talking about.

2019 DSSD which was running really slow (losing minutes every hour) that I just sent to RSC. Will update when I get it back

Yes, that's the accepted wisdom.
However, I wouldn't be surprised for the standard to evolve and become more flexible to take into account these new movements that seemingly can run ok with low amplitude
The 32xx movements aren't naturally predisposed to running with amplitudes in the upper ranges to start with and it's understood to be a feature of the design.

Measuring amplitude is regarded as a measure of the health of a movement. It is a non-invasive way of assessing the movement against acceptable norms.

Amplitudes and Rates
A try to explain my view

If a movement has a technical issue, e.g. too much friction at a specific place, then the amplitudes will decrease quicker than Rolex designed for. If you don't compensate this effect by frequent windings, then the amplitudes enter after some time into a critical region (approx. < 200 degrees) and the rates will become worse, i.e. rates get more and more negative (less accurate). This unwished friction continues with time and significant wear will further degrade parts of the movement, hence your watch gets more and more inaccurate.

Example: SD43, purchased in 2017, after 2nd Rolex repair in 2019 gave the following result:
Dial Down position:
Full winding -> 286 deg., 4 s/d
After 10:00 h -> 282 deg., 3 s/d
After 26:00 h -> 267 deg., 3 s/d
After 36:00 h -> 259 deg., 4 s/d
I consider this 3235 running very well because the amplitude loss is small, the +4 s/d can be regulated or adjusted.
For me, amplitude-loss measurements vs. time is the key observable.

So,the reported lack of lube on the bearing and second hand pinion friction and wear should be the explanation on the 3235s affected with low amplitudes and very slow running ?
Any other reasons in a movement that can cause the low amplitudes and time loss ?

2018 CHNR : -10 seconds over 4 months = 0.08 spd = awesome

2020 BLNR : -79 seconds over 42 days = 1.88 spd = acceptable.

Voted, ‘no issues’.



PS: since TT accuracy &gt; SS accuracy, maybe I should buy a PM piece to have a perfectly accurate timepiece

My SD43 had to be sent back after it was running slow. I had it about 1.5 years and just dealt with it until I could not stand it.

-5 secs to -10 secs per day and was worse when I wore it 24/7/

Since returning from RSC, its is 0.2/secs and have had it back for 2 months.

Thanks. You can take e.g. the Watch Tuner Timegrapher App which uses a headphone as microphone. A bit tricky due to the mic. installation in different watch positions and external noise. I tried that too and it works to get a first idea, not as stable as a timegrapher but therefore much much cheaper.

The scatter of some data points on the above Watch Tuner Timegrapher figure have nothing to do with the watch movement, their are noise induced, which can be improved, for sure.

3230 Sub. Bought Dec 2020. No issues.

Currently losing just under 1 SEC/day. Worn probably 4 days per week and dial up overnight.

Don’t have a timegrapher.

Thanks for you feedback!
When did you buy your SD43? It was new?
When did you see first a significant loss in accuracy? Let's say about -5 s/d.

Thanks for your data, I have some questions:
CHNR (2018): Did you permanently wear it on your wrist? How often did you wind the movement? Did it stop during the 4 months?
BLNR (2020): same questions, applied to the 43 days
Note: both watches run a bit slow, i.e. rates (s/d) are not positive. This also depends on your wearing pattern and many other factors.

The 3200 series is a new design and there are very likely other places of potential, significant wear, which will reduce amplitudes quicker than designed for. PLEASE, let us focus on data collection and no speculations where the problems could be and if they were already solved or not.
