Bas I'm just curious if you've seen this issue with other Calibres with 70hr power reserve like 9001 or 4130 or 4161? Do these movements have low amplitudes as well?

[CharlesN]

Bas,
Wow,
Firstly .. hgreat photos.
secondly, thats great info.
You now have one very happy customer I am sure.

I have noticed that you say that elves are employed to polish the platinum .... I bet you are one of the amazing elves that look after all our watches so well.

Are you saying that I have funny looking ears?

Bas, thank you so much for your contributions in this thread and elsewhere on the forum!

It gives me a little comfort to see a freshly serviced 32xx doing "only" 208 degrees after 24 hours. My Sub41 is around 192 degrees after 24 hours. From all the expert opinions, this seems to be low (and below the spec of 200 degrees), but perhaps not as dramatically low as I had thought. I contacted RSC in the USA and they said not to send mine in based on amplitude alone because the timekeeping itself has been very good. I am waiting to see if it changes over time...

Saxo, CharlesN and others... great work keeping the thread progressing forward!

I wouldn't worry about it too much just yet, but it is a sign that it will slowly lose amplitude and might need a warranty service in the near future.

As for the one I freshly serviced, it will most likely gain 10-20 degrees on average once all the lubrication is settled.

I have the following question concerning my 3235 data, displayed in Figure 1 (post #1262).

If one would regulate from X = +4,7 s/d to X = +1.0 s/d, how would that impact on the amplitudes in the H and V planes?

I'm not worried that my watch is running a bit fast, just curious to know what a regulation would do for the amplitudes.

Such a small regulation would have no noticeable effect on the amplitude.

Great, very interesting!

Where exactly do you regulate this caliber to reduce the average rate from +5 to +1 s/d.

Can you do that without dismantling movement components?

For my Rolex serviced Sea-Dweller 126600 (3235) I can NOT confirm an increase in average amplitude 19 months after the service.
See graph below.



- Top: average rate (X-Rate) before/after service.

- Bottom: average amplitude (X-Amplitude) before/after service.

- The average amplitude increased from 196 degrees (before service) to 264 degrees (after service).

- Then it remains very stable since about 19 months, until today.

- The amplitude error bars for X are large because the amplitude difference in horizontal (H) and vertical (V) caliber positions are not small, which is normal for all Rolex movements.

- I consider my Sea-Dweller is running very well and stable after the Rolex service.

Just because yours didn't slowly increase in amplitude, doesn't mean most don't.

From my experience a watch will generally gain 10+ degrees of amplitude in the first few days after a service.

And this is specifically the case in the ladies movements (21××, 22××). Where you often have trouble reaching 260° fully wound, horizontal position after it's freshly serviced, and will easily hit 280° in the same position a few days later.

Hi Bas
I have attached some results from my wife’s DateJust with a 2235 movements
The first set are from pre RSC regulation
The second is on its return and then in brackets the next day
The bottom set is from yesterday prior to the watch going back for Rolex to try and do better
Do you have any comments on these results ?

That is right. I say that I can't confirm for my watch. I deliver data, you don't.

Point taken. Can you provide data which confirm that some 32xx indeed imcrease about 10-20 degrees in amplitude after a service? Let's say for a few (5) watches?

I measured my 3235 on the day I received it back from Rolex service. I'm sure that is was thouroghly tested at Rolex before I got it back. So it might already had gained in amplitude on the day I received and measured.

We are discussing 32xx and 31xx calibers here.

Here is an updated plot with more information.




- Now the amplitude X-values are splitted in horizontal (H) and vertical (V) test positions (planes).

- Horizontal plane: DU, DD positions. Vertical plane: 3U, 6U, 9U positions.

- Consequently, the error bars (standard deviations) are strongly reduced on each H and V data point.

- For this 3235 caliber there are no indications that the amplitudes in the H- or V-plane changed significantly over time, at least during the past 19 months.

- Maybe the quality of the service plays are role too?

- Another observation visible in the plot: For about 10 months (387-685 days after purchase) I did not check this watch with my timegrapher. During that period the amplitudes decreased a lot, undetected. I only saw a change in timekeeping from X = 0 s/d to X = -11.6 s/d.

HiBoost, a warm welcome back here!

You own a very interesting new Submariner 126613LB (3235) bought in January 2021.

Can you please update the data you presented here (24.01.2021) with a set of new timegrapher measurements?

Maybe not 'only' after full winding plus 24 hours later but also along the entire power reserve?

Such PR tests in DU position (or other positions too) in order to compare with several studies in this thread.

The more data points the better, as we all know and agree ...

Absolutely agree! We're lucky to have someone like Bas on this forum to enlighten us with the nitty-gritty of the Rolex movements. And we're lucky to have Saxo3 and Charles that keep posting useful info on this thread that benefit all true watch enthusiasts!

Comparison, 3235 vs 3187 data, both after full winding (t = 0)

Figure 1: caliber 3235, purchase date Oct. 2017, serviced Oct. 2019, data 11.05.2021



Figure 2: caliber 3187, purchase date Sept. 2017, no service, data 11.05.2021

Nothing at all to argue and very happy with both watches, the Sea-Dweller and Explorer II.

My DJ41 is back from service and ready for pickup. I’ll see if its accuracy is improved. Fingers crossed!

Then it took only 4 weeks instead of the 4 months (announced by AD).

Please post your timegrapher data here.

All 5 positions, after full winding and 24 hours later (same as in post #1259)

Don't forget to wait a bit after full winding and after each position change, for movement stabilisation.

Good luck.

[andschmi]

My OP41 is zero seconds off per day. Pretty happy so far.

All sounds great for you. Well done

But. Are you checking against a clock or similar by eye or are you, hopefully, checking with a timegrapher.
If you don’t have one, are you using an app on your phone such as WatchTracker.
We also need to know the history of your watch …. Such as purchase date and if any work at all has ever been done.

If you don’t have a timegrapher it might give you fun to have one …. They are inexpensive on Amazon. The model 1000 or 1900 are great. They only have one problem in use …… They are addictive.

I've 124300 OP41 and I'm going to finally purchase a timegrapher from amazon. The "timekeeping" seems to be excellent on my watch so far.. I'm comparing it to my phone clock and it seems to gain no more than 7 seconds per week which is brilliant for me. The watch was purchased in November of last year.

I have the 1900 model.
There is also a 1000 model.
Those 2 seem to be the popular models.

I think they are the same apart from tne size of screen.
The 1900 is usually the more expensive as it has a larger screen but, If you look with care ... Amazon had it for less than the 1000 when i bought mine.
You really won't be sorry you have bought one.

Found the weishi 1900.. I'm ordering this. Not bad for 175 £

The OP41 Ref. 124300 is interesting for this thread because it is equipped with a 3230 caliber.

So far I have not heard any report of problems for this movement.

I'll start testing as soon as I get the timegrapher. I haven't read or heard anything either. Fingers crossed it stays this way.

[CharlesN]

Hi Bas,

That is great information on what you have found needed to be changed.

Very informative and helpful.

Thank you.

[saxo3]

@Omarion07
Any feedback about #1258?
All clear?

[Andad]

Hi Charles,

When was your wife’s DJ serviced or is it fairly new.

I’m not impressed with the precision.

Are you?

It has not been serviced or anything. Only a regulation a few weeks ago.

Am I impressed ... Simple answer .... NO !!!
