I’ve found the Weishi timegrapher to be excellent for detecting strange noises that occur when something in the escapement is touching something that it shouldn’t. When the tracings are irregular or wild, it’s time for the microscope even if it’s keeping time in that position. It’s been a great tool to have! Another great video, Alex!

You're exactly right. For hobbyist watchmakers who gain satisfaction from making an Ebay vintage come back to life and run well again, the Weishis are absolutely fine for gauging skill level and accomplishment. It's doubtful it ever happens, but if this hobby ever graduates to working on more expensive watches, I'll upgrade to a better timegrapher. In the meantime, my old Gruens and myriad ebauche watches will do just fine with a Weishi. Thanks, Alex. Your videos are always thoughtful and well presented. I've learned tons from them.

Thanks for another great video. In my experience the Weishi should generally be taken with a grain of salt, and perhaps even the expensive Swiss timing machines. Also in my experience the gain setting affects the amplitude reading quite a bit. To be sure I record a slo-mo video of the balance. Anyway, the Weishi is good enough to make sure things aren’t completely off.

Curious how the Witschi machine would stack up against the Weishi -- basically if they're truly identical internally, or if the components in the Swiss version are better, or perhaps calibrated to a higher standard? That software you're using looks cool too, but how do you hook up the microphone?

Excellent video - thanks. The very short test duration will also amplify any differences shown by the measurements. Can your calibrated software record and average readings over a longer time period as well as provide instantaneous readings? It would be interesting to see the test repeated over a 24 hour period, when the watch timing could also be measured against an atomic clock. I appreciate that declining mainspring torque may have an effect over the longer time period, but still think the result will be interesting.

That's a good and honest comparison Alex. I recently bought the Weishi 1900 and it's a great little machine and is a confidence boosting guide that you are doing something right when comparing a pre and post service. Just finished servicing an ETA 2783 that indicated low amplitude on the Weishi. Post service it's running like a champ with good amplitude, beat error and rate. One question/observation - I do notice a difference in readings depending on whether the watch is cased compared to uncased or in a movement holder as compared to sitting directly on the stand. Do you think the microphone is affected by resonance from, for instance, a movement holder?

Thanks again Alex, as always with measurement tools they need to be calibrated regularly but I don’t believe there is a facility available for the weishi timegraphers. I have experienced very expensive and regular requirements for calibration from my days in electronics many years ago. I don’t believe that with the tolerances needed in watchmaking it is too big a deal, the original railroad watches there were no timegraphers available to them.

Have to add, I also worked in electronics companies where calibration was less important and our repairs were fit for purpose.

remember too that there is software in both of those devices that will make them not completely comparable. I was a research scientist for years and whenever we compared data from different devices, we would frequently have to utilize another program to directly compare the results. For example, both of your datasets have 'smoothing' applied. That, in itself is an equation. What would be better is to open the movement, and utilize optical references to determine BA and AMP, and then run a multi-day test to judge accuracy, then compare back to both programs. I would wager that you'd then have 3 disagreements of data.

It depends on what you are going for. If you are just trying to see how accurate your watch is you don’t even need a timegrapher. Just check it against an atomic clock or quartz movement.

There are test instruments for your more expensive time grapher to set it up from factory. Maybe its + or - .0000001 sec as pass and fail but all are very close to that initial calibration. This is way higher than the 1900 cheaper versions. Is like comparing a Rolls Royce to a Toyota Corolla. Both transport people and items so the end result is the same. For the 1900 you do a baseline test before any work to see how close you are to 0 secs and respectable amplitude. looking for a straight horizontal line. You are doing a good job if you achieve your goals using a 1900. It is a hobby and not trying to get absolute ultimate results. The watch runs better than before the rebuild.

For the life of me (I´m not a pro, just a hobbyist) I have not seen an explanation on how to adjust to several positions. Do you measure first them (4, 5, 6, 8 whatever) and then average them out and adjust accordingly? If so, you need to adjust always (correct me if I'm wrong) in the dial down position which is the way you gain comfortable access to the regulating organ whatever it may be. So If you dial perfectly one position, I think the others will be thrown off...how is this accomplished? I dunno if this make sense, please help me, I haven't seen a video or a text going thoroughly with this topic.

I think what these timegraphers lack is an external reference. A suitable external reference would be a low cost GPSDO or any inexpensive GPS module, 10Mhz and 1 pps output. In this way these instruments would be referenced to the GPS system and atomic clocks (actually you could also use WWV this is what old calibration labs used). Second, once the lab has a good GPS external reference, then this reference could also feed a very inexpensive Chinese made DDS function generator with a external reference input. The signal from this DDS function generator could then stimulate (pulse) a piezo electric sensor/vibrator mounted to a piece of round flat stock (brass). In this way you could make a watch simulator, to test your timegrapher. Because the watch acoustic signal is low frequency the DDS function generator pulsing a piezo electric vibrator should work to simulate a watch.

What you are talking about makes sense, its probably similar to the way timegraphers are calibrated. I know my timegrapher software that I use calibrates itself with something like that.

Lets consider this as an "unfair" test or comparison. Chinese timegrapher was off by several seconds againts the software timing machine. But how about the software? Is it accurate enough for timing solution or inaccurate enough compare to standard reference? When it comes to accuracy of the timer or timegrapher. The issue is how accurate or better to ask how stable the timebase is? Cheap timegrapher (in general) doesn't offer stability with temperature changes. Its not my opinion, it's a fact. Any timebase reacts to temperature changes and this changes affects the accuracy of the timer. Now, which of them telling us the "true" rate error of the watch? The software or the Chinese timegrapher?

@@OvidiuHretcanu it’s probably pretty close. You can always set the watch to an atomic clock and then track it over a 24 hour period of time as you wear it on your wrist. That’s really what’s important.

@@watchrepairtutorials yes indeed, for the time. I was curious about the beat error, which is not something you can double check. But then again, if I don't have the tools for that, it means also that I don't need to mees with it either :D (that video about magnetism was a savior for me. Managed to correct two pieces myself).

The lift angle of that movement is 50 degrees not 52. The Weishi will give the wrong results unless the lift angle is set correctly.

The problem with timegraphers is that who know what noise it will consider as part of the tick. For perfect accuracy and to be able to check for other noises one simply need to have to look on the sound pattern. In addidion to avoid wrong readings the intensity threshold stting is mandatory. Escapement analyzer if you can afford it or Watch-O-Scope for free with a simple piezo disk is perfect. If this is not a requirenment it makes no sense to buy any timegrapher. The watch apps are perfectly fine.

The professional grade analyzer ; how did you "calibrate" that? You mentioned the error range for timing but not the other measurements. You're only as good as the calibrator that is doing the calibrating. And if your calibrator isn't calibrated properly....

So for the home hobbyist, the rate being off a couple seconds/day doesn't amount to much and that's okay. But the key is that if the Weishi amplitude was off by 15 degrees and the lift angle was off by 2 degrees and you don't want to make matters worse by guessing on the lift angle because everything adds up to 25 degree difference (or did you mean 17 degrees?), this level of inaccuracy won't help us diagnose amplitude problems. Sounds like that could be a frustrating, never-ending, rabbit hole for the home hobbyist! Given that, how would the home hobbyist then be able to diagnose amplitude issues with this level of inaccuracy? Not sure I want to purchase this machine? Any thoughts Alex? Thanks as always for your vids and expertise!

Perhaps the big takeaway here is to get the lift angle right. If a machine is off calibration by 5-10 degrees of amplitude by itself, that's not a huge problem, but add that to lift angle that is off by 3 , now your results OFF by 10-25 degrees and That is a problem when troubleshooting issues with rate.
