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 £

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?

That’s about the correct price
Hopefully you have Prime so it’ll be delivered tomorrow.

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.

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 ?

Hi Charles,

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

I’m not impressed with the precision.

Are you?

Your measured average (5 positions) rates and amplitudes are:

Before regulation:
X (rate) = -13.4 s/d
X (amplitude) = 220 degrees

After regulation plus 2 weeks:
X (rate)= +6.2 s/d
X (amplitude) = 254 degrees

Don't know what the expected values for 2235 movements are.
But the regulation was definitely a significant improvement.

You did not sea the verbal 'trap' ...

I agree the regulation showed a significant improvement from an average of -13.4 spd to now +6.2 spd but I also think it could and should be significantly better.

I always think a watch should never loose time as it results in its owner always being late.
A watch should only gain a minimal amount. Being early is fine as one has the option of delaying the arrival time if only by walking slowly.

I choose to not notice possible "Traps" with wording such as the Precision, Accuracy and Timekeeping definitions.

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.

32xx movement problem poll and data thread

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.

I delivered data and answered a lot of your questions, and this is how you act?
This isn't the first time you're being a **** towards other members. Have it your way then, you're the first on my ignore list.

Amplitude is good, but it does need further regulation.

I saw no precision in those results no matter the average.

Take real care.

Please !!!

Come on guys,
Please ...

There really is no need for name calling or anything near what has just gone on.

We must all agree that it really is unacceptable even if the outrageous name calling that has thankfully been edited has been replaced with slightly less profane wording.

Let us all try and remember that we all are here for one thing only ... Our love and interest in watches.

My native tongue is English so I think I may have a slight advantage over some of you who are not either English or native English speakers.
It is far too easy to get misunderstandings from slighly wrong wording.
Please think first, Count to at least 10 before getting upset. Just tke a moment to reflect.

Please, plaese take it easy.

So, now everybody, "Kiss and make up" (an English phrase) and get on with each other nicely as we were all doing before.

This is my rant over now.

Thanks for that.
How much better do you think it can be got ?

i was always led to beleive that the smaller size movements were much harder to get running well than the larger mens movements..

I dont know how much truth there is in that, But, I bet i know a man who does know (Ps That's you !)

While I agree that my aggravated post was crossing the line, I am still done here.

I promised data, provided detailed data, answered all questions as thoroughly as possible. I get an arrogant response from Mr Saxo.

Why would I waste any more of my time taking pictures and posting to this thread?

During my absence in the beginning of this year, I was merely logged out and didn't check the forums every day, I did however check frequently enough and have seen Mr Saxo post in this arrogant and sometimes almost as rude as I just was, tone, towards people that I value and like on here.

I do not respond well to such behaviour, not online and not in real life.

Hi Peter,

Hey. That’s going a bit far I think.

Some of us, my self included, are not only learning from, but enjoying this thread and have had quite a bit of fun participating.

These threads are on an open forum and as such will attract differing views and points of view

Why would you even consider ending a thread that is alive and well and thriving and educating.

I know you were a moderator, perhaps you still are, I don’t know, but it’s just plain and simply wrong to end something just for a momentary lapse in agreements.

Completely agree Charles. This is, by far, THE most informative thread running on here at the moment, so I can't remotely see why it should be ended prematurely. People don't have to read it, or participate in it, but those who do should be able to continue to do so.

It's the only technical one we have. I appreciate all the data you guys are collecting and as an engineer I find Saxo's pedantry to be an endearing quality.

I agree with Charles as well. It's not fair on other members that this thread gets completely shut down. All that happened is a misunderstanding between two valued members of TRF that contributed a lot to TRF. Many things can get lost in translation in any form of communication let alone written communication. We're all adults here and the love watches brings us here to escape from all the s**t that goes on in the world. I hope we can move on from this and it's all water under the bridge.

Probably the only thread that I check on daily basis. No interested in the daily wristshots and availability/discontinuation threads that are getting really old tbh.
