YaeTekWatch Timing Machine Tester Tools Multifunction Timegrapher

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'm a hobbyist, and service some of my old vintage watches/pocketwatches.This thing is great. there's a bunch of these weishi ones rebranded for other stores/companies so they all work the same. The timegrapher itself works as described by many folks on the 'net. The instructions are ok, but there's enough folks online, and it seems pretty straightforward. One thing is i couldnt really figure how to change sensitivity/gain - i think i know but i just press buttons til something shows up. I'll check online later.I've checked everything from my mom's small ladies watches to my big sized 18s pocketwatches, and they all fit. Someone online had said max size was like 50mm but i had no problem shoving a 58mm pocketwatch case onto it. I dont know if i can test positions on the larger pocket watches as the clamps probably dont grip those larger ones well enough, but i'm sure its easy enough to jury rig some strap onto it to keep it seated. I mostly tested with it upright.I regulated the slow way: adjust regulator, check back in a few hours, adjust again. I shoved one Waltham pocket watch onto it that i've regulated, and it was reading +38s/day. I readjusted it, shoved onto the timegrapher, and it read +16s/day.... it was GREAT seeing how fast i can now regulate watches. I adjusted again and now it's about +3 seconds/day face up position (i'll leave it like that).I double checked Omegas/rolexes/seikos. Was great seeing some of these watches be so accurate. My omega planetocean of over 10 years is dead on, with almost zero beat error. exciting!It also helped me find some faults as well. I was kinda speculating some of my pocketwatches were out of beat and the timegrapher helped show that.the timegrapher won't pick up anything if the watch is completely out of whack and needs servicing big time. It's helped me regulate faster on watches that i have serviced myself. Overall i'm really happy with this product.

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.

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.

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.

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

Works great

Works great for checking how the timepieces are running.
