A 32xx watch can still run very accurately although the caliber suffers from too low amplitudes, this is measurable (with a timegrapher) after full winding (t = 0) and at t = 24 hours.

The main observables are the caliber amplitudes in all 3 vertical watch positions. By opening the caseback you have no chance to 'see' that.

I agree with you that +1 s/d is a 'fine performance'.

I installed the Timegrapher app on my iOS phone and can take measurements for the community. Please tell me how to do it correctly. The app indicates that it is too noisy (but it's actually quiet) and where is the best place to place the watch. I will share my results with the community.

Did your friend scare you before or after you purchased this piece? Not that it really matters at this point. If you are truly concerned take the watch to the AD and let them put it on their timegrapher, 5 pos test. This will do two things for you dead away. 1. It will tell you more conclusively the state of affairs with your watch. 2. It will also give you a baseline data set to tell how well your phone app is reading.

He is the owner of a service center in another country. Even before the purchase, he told me I should get the 31xx, but I specifically wanted a new watch from an authorized dealer.

Here is an example of why just say you are running at +1 dial up is inconclusive. These readings were taken in Jan24. You can see dial up is great +1.9, but 9up is way off, the amplitudes are out of spec in the verticals.

After 26h DU amplitude is still around 270-264, rate is 0, +1s.

Is this after a full wind or after 24h? :(

After 24 hours, see post #4661.
Watch 126610LV, caliber 3235, bought 05/2023.

The 3 vertical amplitudes were already too low when EasyE measured with his timegrapher on 30.07.2023, so about 2-3 months after purchase!

Did you write this to me? I agree with you; I'll check the amplitude after 24 hours tomorrow.

After 36h DU 255, CD 225. Rate the same 0, +1. Time for testing is done for now. Time to Explore :)

I took the measurements after 36 hours (I couldn't do it after 24 hours). I used the headphone microphone. Honestly, I was encouraged by the results. However, I should note that the watch was in the DU position the entire time, and they have an accuracy of +2 seconds per day over the last 5 days.

Summerise After 36 Hours:
DU 220
DD 212
12U 248
6U 264
3U 258
9U 260

Vertical positions gave higher amplitude or am I missing something? :)

I didn't understand it either, but I don't have a professional device.

All four vertical amplitudes are HIGHER than the two horizontal amplitudes.

The data is complete garbage and proves that apps (can) deliver completely wrong results, some users don't understand their data, and others are resistant to advice.

$200 on Amazon

As I stated earlier, take your watch to an AD that has an in -house watchmaker. Let them run the 5 position test and get their readings. Hold on to those and check back with them in 6 mos to a year. Or get a cheap tester, ditch the app. If you are really worried about your watch.

I have a BLNR purchased 7/19 that the warranty is about to roll off. Actually looking quite good still.

I did it because it was at hand. I will go to a watchmaker, but that will be next month, unfortunately, I don't have time now.

Was there any recorded case of 32xx with amplitude 300?

An amplitude of 300 degrees is realistic during and post-service.

Someone else would have to answer that one; I only see watches with problems. Theoretically, a new watch should have amplitudes comparable to a freshly serviced watch.

I have seen 5 of them brand new, with amplitude range from 260-280 lift angle 53. None was even close to 300. That is why I ask.

I placed an order; the timegrapher should arrive next week.

Good thing is that for example this one, after 60h have great a daily rate despite low amplitude

The highest value I have ever seen was 293° (DU) and 289° (DD), which I measured (with a professional timegrapher) for my SD43 (3235); watch was running fast (X = +4.3 s/d).

Short answer, no for any 32xx movement.

Correct, I confirm 260°-280° in horizontal positions.

Please, delete this app and use an inexpensive timegrapher!

No I will not, because this app is great. I have compare its data with a professional timegrapher numerous times and it was scary close. Only beat error was always shown as higher. But rate and amplitude were super close. So thanks, but no :)

While I won't claim it's common to see 300, I will say that it is an amplitude I have seen once or twice during preliminary & final timing during a 32xx service. It's typically between 270 to 280.

I understand that you are a senior L40 watchmaker working for a Rolex AD.

With all respect, can you please show us only one 'complete' (5 positions) Witschi timegrapher measurement of a 32xx caliber, as a Witschi screenshot, with 300° amplitudes in dial up and/or dial down?

In the meantime, I quote what Bas (SearChart) had posted (April 2023) in this thread:

"We don't see 300 degrees because it's not designed to run at those amplitudes.

The entire point of the chronergy escapement is more efficiency and less friction, very high amplitudes would be counterproductive since it's just a waste of energy.

For a 0hr test DU DD amplitudes are optimal when between 260-280, and vertical position in the 230-40 range.

Pretty much all 32×× that run like this will have good steady average rates both at 0hrs and 24hrs and will reach the minimum amplitude tolerance of 200 degrees easily. So I see no point in aiming for 300 degrees, there is no benefit to that.

The only thing I want to see is that they keep running at ideal amplitudes for 8-10 years. Simple regulation isn't going to solve that problem.
