Quick compare test between Weishi, Witchi,TYMC and Vibrograf

This video was an after thought, so i had to make do with the footage i had.
Never the less, i hope you enjoy.
The conclusion is that as most watches have an factory accuracy of a couple of seconds a day the need for a timer that allows you te regulate in milliseconds doesn't make any sense. Any timer (old and new) within your budget will allow you to regulate your watch just fine. It's the bells and whistles you pay extra for.

The Master Watchmaker I am being taught by has an incredibly sensitive calibrated microphone that produces an output that can be seen on a computer screen. The microphone signal allows you to see three separate beats generated per watch beat. One being the balance jewel hitting the pallet slot and fork, another the pallet hitting the banking pin, and another the escape wheel locking face hitting the pallet jewel locking face. The image looks like that of a seismograph. It also displays the positions each set of readings are taken from, but not as number, but letters instead, like DU for dial up and so on. Interestingly he also has a Weishi 1900. He has been a watchmaker for the best part of 40 years.

Thanks for the comparison. The Vibrograf B200 (without the amplitude measurement) can be found for about $200 used on ebay these days. Otherwise, I think that you got most of the pricing pretty accurate. Ultimately any of these will do the job just fine as you concluded.

thanks for posting this 👍

В самом начале видео на столе лежит Ракета ролекс со стрелками от Коперника. И как она туда только попала))

Great video. I know the Weishi 1000 just has its own "ticking" noise that it plays to represent the signal it's receiving from the watch movement. But some of the more expensive timegraphers have a speaker that amplifies the real ticking of the movement that the microphone captures. It sounds like the old Vibrograf unit in your video has this feature. What about the more expensive Chinese ones?

i was wondering the same did u ever got an answer?

[@jackprick9797]

Thank you for making this video. I am thinking about getting a time grapher and was wondering which of these cheaper units to get. I would use a bit different logic than used in the test. Without a calibrated device with known error, it is difficult to say which machine is most accurate. Even if two of them agree, they could still have the highest margin of error. The logic I would use instead is that the professional machine is most accurate (I assume it gets calibrated every 1 or 2 years?) and so the time grapher closest to that machine is the most accurate. By that logic, that would be the TYMC correct?

Hi Jack, Yes, i guess you are right. The TYMC wins again. Thank you for watching. :) I'm glad it was of use to you. There is also another consideration, most watches that i dare to touch with my amateur hands are rated for a diviation of 5 to 10 seconds per day. In this test the difference between the timegraphers is so small that it would not have mattered as the watches i work on are not capable of that level of accuracy. I hope that I makes sense.

Great video.
The B200 however doesn't burn the graph but rather uses a carbon Ribbon to print

[@watcherror]

I had to check the original manual "The paper used with the Vibrograf B 200 is a pressure sensitive chemical paper and no ink ribbon is required." Looks like i was wrong either way. :) Thank you for your comment!

@@watcherror when you open the hood you'll see a ribbon rotating between 2 reels, the ribbon goes between the part that makes that ticking noise and the drum with the helical line over it

[@watcherror]

@@Inkreptile I'll look into it. Thanks for the tip.
