YaeTekWatch Timing Machine Tester Tools Multifunction Timegrapher

Very good product a must have if you a watch collector .. Got to know how your timepiece is working and it will tell ya when it’s time for an overhaul.

Works great

I used this Weishi 1000 Timegrapher to successfully regulate my first automatic (non-quartz) watch, which consistently ran 10-12 seconds/day slow. (I took the watch to three watch shops and I was told three times "it's within specs.") After watching many on-line videos about how to adjust an Etachron regulator, I figured I'd give it a whirl. This timegrapher performed perfectly and I was able to check the watch's accuracy in multiple positions with the rotating and tilting microphone stand. Note: you need to know your watch's "lift angle" which you can easily set on the timegrapher. After that, using the timegrapher is quite intuitive. It's a very accurate and sensitive instrument. It took four or five very gentle nudges of the regulator back and forth, but I got the watch where I want it within ten minutes of effort. I would recommend this to anyone who willing to open up a watch and make microscopic adjustments.

I have had this for a couple of months now and it works perfectly. If I had it over to do, I would probably buy the 1900, but there is nothing wrong with this 1000 for the lower price than the 1900 model. Invaluable tool for regulating a mechanical watch. You can see instantly the watches' performance.

This works great although it’s not perfect. It does tell you the beat but it’s hard to adjust by just using this. I set my watch in the morning and I wear it all day then box it at night. Check it in 24 hrs to see how fast or slow it is running. Put the watch in the machine, dial down and see how many seconds it says it’s fast or slow. This number may be different than your real world number you have for 24hrs but the machine will give you a number to go by. Just move your lever on the watch movement plus or minus how fast or slow your watch is till it changes that amount on the machine. Doing this I’ve gotten my San Martin to plus 6 sec a week ( this movement from factory is +- 15 to 30ish sec a day). But it would have taken forever to do this without the machine. The machine is easy to use and very nice quality.

Have had it for a couple of years and still working fine. Very useful in tracking your watch health.

It’s a game changer

Great tool to check your watch if you have many of them. Good investment for a watch enthusiasts
