The 31×× and 41×× don't have serviceable barrels anymore either unfortunately.

Is the lack of power reserve another symptom? I used to have bad timekeeping (+/- 4 sec.) with a power reserve working as advertised (70ish hours)… now I have timekeeping within COSC specs but the power reserve is very weak (less than 48 hrs)

I have not observed that for my 32xx watches, but a reduced power reserve (48 instead of 70 hours) will become visible as soon as amplitudes are well below 200 degrees after full winding.

I used to have bad timekeeping (+/- 4 sec.) with a power reserve working as advertised (70ish hours)… now I have timekeeping within COSC specs but the power reserve is very weak (less than 48 hrs)
That does not sound good…
How do you determine (measure) the power reserve?

1. +\- 4 is actually better than COSC (+6/-4)

2. Are you measuring from when you fully wind the watch and then set it down, or when you take it off and set it down without having recently wound manually?

3. Not seen anything in this thread suggesting this is a symptom.

Nothing scientific… just check every hour or so. But there is no question that the power reserve has significantly dissipated.

1. Meant COSC superlative +2/-2 as advertised
2. The latter, but my wearing behavior is quite consistent
3. Good to know, thank you

In that case, wonder if you have some other, unrelated, issue with the automatic winding, where it’s not getting fully wound on the wrist. Try fully winding manually, then setting it down and checking its PR.

< 48 hours is very likely not the power reserve (PR) of your watch.
What to do?

(1) full winding with 40+ full clown turns,
(2) read and note time,
(3) don't wear watch but set it down in dial up (DU) position,
(4) don't touch watch,
(5) wait until watch stops running,
(6) read and note time,
(7) calculate difference (6) – (2) in hours : minutes : seconds,
(8) that is the PR of your watch (in DU position),
(9) post result on TRF.

Nothing to do at all with science

If only all customers knew this, it would take care of many perceived power reserve issues.

It's rude to say but I sometimes wonder how some individuals even manage to acquire enough funds for these watches, when basic things like setting the date is too challenging for them.

FWIW, I've tested the PR of my watch both ways (just taking it off after wearing it for 16 hours a day - every day) and also by winding it 40 times from a dead stop. It went over 70 hours every time.

But lately, I've been meaning to test it again (40 winds from dead) because the last time I let it die (from just wearing) it seemed to only go like 55 or 60 hours. I could have been lazy that week.

And also, for what it's worth, my watch is running at a steady -10 spd for the last few months. At least it's steady.

Warranty is up in June - 2023.

That's because you're looking at it all wrong, given where the money-making seems to be. I often say to myself:

If I were 20% smarter, I could make 50% more money. If I were 30% dumber, I could get rich.

Put my 323O Sub to Weishi 1000 timegrapher. Dial up is spot on at 0 s/day. Good amp 272 at 53 degrees lift angle. On the wrist since new it has run on average a bit slow -1.5 s/day. So, I’ve put my concerns to rest.

Without measuring all 5 positions (CH, CB, 9H, 6H, 3H) your conclusion might be wrong.

I also think there is an element of luxury which to some customers almost discourages learning such things. Much in the same way that a wealthy person may have a nice car, but a very rich person has a driver. Almost to imply operating the machine is beneath him. At my AD, there is a procession of old rich ladies who come in the first of any month where the date needs to be corrected

Hi Bas,

My previous reply was t i c because I can’t think of any other way to check PR?

How else can it be done?

SeaDweller 126600 Data

Below (or attached) is the data I collected from my SeaDweller 43 126600.

The first set of data is from September 2020, six months after obtaining the watch. I included these measurements in my note to the Rolex RSC indicating that there is obviously an issue.

Eight months later, the watch was sent in again to the Rolex RSC for another set adjustments/fixes/voodoo/holy water. The second time appeared to stick as the watch has since run well after the second trip.

The second set of data is from November 2022. Sharing now as I am trading in the watch. I have come to the conclusion that the watch is too big for me.

It is obvious that the 32xx series math work correctly (mainspring tension; lower amplitude, smaller escapement); once the issues addressed, the watch runs well in all positions and environments. It's also obvious that the 32xx movement is susceptible to serial manufacturing-isms when production scaled up to the more popular Rolex watch models. My 126710 GMT was sent back three times while I owned the watch.

The watch I am wearing now is a 39MM 214270 Explorer I (Mark II dial) with a 3130 movement. It's solid on the timing machine (good amplitude, solid line on the readout).

SAXO3 encouraged me to post my data so here it is.

As I understand your timeline...

1) March 2020 watch is acquired
2) Sept 2020 you sent the watch to RSC
3) You received it back
4) May of 2021 you sent the watch back to RSC


You measured it for #2 but did you ever measure 1, 3 or 4? Even if you don't have full data to post, the general trends would be interesting. For example, did it actually get worse from 1 to 2 or was it low amplitude when you received it? And did it come back at 3 with a higher amplitude only to drop again by 4 or did it never have its amplitude restored in the first place?

Yes, correct. After the second time to an RSC, the watch has been performing fine.

My gripe is that I never have had to send a Rolex to an RSC that had a 31xx movement, but with the two 32xx movement watches that I have owned (126710 and 126600) both watches required two laps to the RSC before they performed as expected.

The new 32xx movement, once whatever voodoo Rolex does to it at the RSC, runs exceptionally well, but getting to that point is unacceptable. It appears that the first time I send a 32xx movement into an RSC, they inspect, regulate faster and call it done. On the second RSC visit, my guess is that there is a movement rebuild, or replaced movement. Unfortunately, I did not record the movement base plate serial number(s) before sending to Rolex RSC. The wait time (three weeks) is the same whether its the first or second trip to a Rolex RSC.

Not for #1 as the watch was new and not problematic

For #3, I did a quick measurement but did not record because I expected the watch to be problem free after the first trip to an RSC.

For #4, I am sure I measured, but I did not keep the recorded measurements.

Going from memory, the watch had what I considered low amplitude from the beginning, but I learned later that was by design. The 32xx movements have lower amplitude and I was used to high 200s to low 300s amplitude numbers that we see on the 31xx.

Your summary is correct; degrading performance over time to the point which it was obvious that the RSC has to address it. I am always fearful that Rolex RSC would receive the watch and say that there is no problem. I would wait until the performance would degrade to the point were amplitude was less than 200.

Thank you for helping me clarify and thanks to SAXO3 for leading the discussion on this issue.

Sheldon, I had a look at your SD43 data tables (post #3264).

The timegrapher lift angle setting was 53 degrees?

I plotted your 5-position November 2022 data, which are interesting to me.

After the second RSC repair, your SD43 (caliber 3235) seems to perform very well, at least for 50 hours of the approx. 70 hours power reserve.

Another data point after about 60 hours would have been very nice.
Did you do measurements during the periods 23:00 – 01:00 or 05:00 – 08:00?

Clarification of the watch positions you analysed with your timegrapher:

Face up = DU
Face down = DD
Crown left = 6U,
Crow down = 9U
Crown right = 12U

Rolex regulates the 32xx in 5 positions except 12U.
Therefore, normally crown up = 3U is measured instead of crown right = 12U.

I just received my Weishi 1900, set the LA to 53 and I am now collecting data. I have a couple of questions.

1. Is the LA the same for the 31XX movements? I want to take a reading on my previous gen sub as a comparison. So is that 53 or 52?

2. What duration do I need to let each position run for a good reading? My first few runs have been for 15 mins each. Is that long enough?

The lift angles are 52 degrees for 31xx; 53 degrees for 32xx.
One does not need to run 15 min for each position.
I had posted a step-by-step procedure in this thread, will try to find it again.

You need to do a full winding with 40+ full crown turns
Wait some 15 min for stabilisation before the first measurement.
I measure 2 min in each position with a stabilisation time of 2 min after position change.
Measure all 5 positions: DU, DD, 3U, 6U, 9U

If your "run" time = "measurement" time then it is 2 min in each position.
After position change wait 2 min for stabilisation.

What is curious, in watching the screen through the 15 min interval with the watch face vertical I saw the rate and the amplitude bounce all over the place with one of my watches. Like rate would go from -1 to -4 and the amplitude was bouncing between 214 and 220. Like maybe every 15 seconds or so.
