Timegrapher No.1900, Multifunctional Watch Tester, Watch Timing Machine for Watchmaker, Watch Calibration Tool with LCD Screen

Great to check the health of your caliber, regulate the movement, and it's just plain fun. I have a vintage omega seamaster 300M, among a few other omegas. I had it serviced recently after it stopped working. It took omega 3 months before it was done. They included a sheet stating that it was regulated to +4 seconds, a day, within cosc standards. I was excited to open it up and picked it up on the cushion, which was top heavy, and promptly dropped it. Felt like I fumbled the ball on the goal line with seconds on the clock. I set the time and put it in my watch case, came back 24 hours later and it lost 10 seconds. I tried setting it face down, 24 hours later it was another 11 seconds slow. I only wear it a couple of days per week, so I hate it losing so much time while sitting in the case. So I bought this timegrapher. I have an inexpensive watch with a seiko NH35 caliber, which runs 15 seconds fast per day, quite good for a NH35, though had a beat error of 1.1. I practiced regulating that and corrected it to +6 per day with a beat error of .2. I then checked the omega on the timegrapher, and it turns out that the average of the 6 positions is +4. It just has significant variation in the different positions. I discovered that if I leave it at a 45 degree angle between face up and 12 down, that it only runs +2 per day. So that is how I store it in my case, and everything is fine now. The amplitude, btw, is averages a great 300. If I hadn't gotten this, I would have lived forever with a watched that I believed to be slow, and be cursing myself about my fumble.

I'm glad I got the 1900 with the bigger screen. I have collected watches since 1970, I have about 100. You cannot believe how easy this thing is to use and the results can be very surprising. Some of my least expensive watches outperform some of the very expensive ones. The pic shows the San Martin 62MAS ($179 on Amazon) performing at -3 sec/day. To put that in perspective, the new "Limited Edition," and ridiculously expensive Seikos, SLA055J1 and SLA057J1 advertise accuracy of +15 to -10 sec/day. The new Seiko 5 SSK033 GMT that I bought in May was running at -56 sec/day. I sent that to my watch smith to fix as that is completely ridiculous. Very nice to have if you collect watches.

Works great but does not save settings for rate, lift angle, etc.

As a hobbyist watchmaker I need this to analyze and service watches. This is a better one, nicer display, larger screen and more options. Works great so far and I expect it to last a long time.

This timegrapher is very easy to use right out of the box. It worked perfectly without even reading the instructions. The default lift angle is 52, you need to input your movements if they are different. The instructions are not perfect, but good enough to explain how to set it up, how to use it, and how to troubleshoot it. Perfect for the watch collector and hobbyist. Accuracy is supposed to be very good, so this might work for professional use as well. Great timegrapher at a great price!

recieved item does not work at all black screen and had to return it. poorly made

Must improve manual. It works but, two watches. Both fast. One shows fast and one shows slow? Auto select not perfect. One shows 18000 and one shows 15000 beat rate.

Works great. Only used it a few times .

Delivered quickly, well packaged and works correctly. I've used it to check and regulate vintage watches. Two colour line indications assist in adjusting to eliminate beat error. Larger display than 1000 version, otherwise functions the same.

It works as described; no issues. I am just using it to track the performance of my watches rather than any maintenance or regulation, but I am quite happy with it.
