New Coaxial MTG Watch Tester Timing Multifunction Timegrapher LCD Screen NO.1900

Works as advertised. More detailed information how interpret the result you can easily find in the YouTube or any other watchmaker forums. The device is popular.

I’ve been building my own custom watches and modding existing watches for a few months now. I decided it was time to go to the next level and try regulating some of my builds.This Weishi 1900 is dead simple to use. You just need to figure out the lift angle of whatever watch you want to regulate. Once you input the LA the time grapher auto detects the rate and calculates everything else for you.The one thing that surprised me when I took it out of the box was that where you place the watch is one metal tab and then a plastic tab (which is held under spring tension). The metal tab concerned me that my watch cases might get scratched. So far, that has not been the case, but I would recommend maybe putting some masking or painters tape over the metal tab, just in case.

Will recommend for watch collectors buyers and resellers. saves us money on watch repairs.

Timegrapher 1900 arrived quickly. Very well packed all safe and secure. Met and exceed my expectations. Would definitely purchase from Seller again.

I am watch hobbyist and bought this to check my watch collections accuracy. This is excellent mechanical watch tool it works right out of the box. Works on Omega Co-Axial movements too. Nice to know the accurancy of your watches and if your up to it tweak your time to +- 5s/d. Product was shipped as described and recieved next day with Amazon Prime boy was that fast I will recommend this tool to all my mechanical watch hobbyist.

I've read where some of these units can be off a bit. Well, I've actually set a few watches to zero beat errors and as close to zero as I can get for seconds per day, generally landing in the +1 to +2 per day and synchronized with my phone. I've been pleased to discover, at least the better watches seem to lock onto that time quite well. In other words, if I set them to +1 second per day on average, they are off by about that much in 24 hours. That would suggest a high level of accuracy from the unit. Doesn't get better than that.I debated going with the 1000 originally, but I have liked the larger colored display. Makes tweaking the Beat Errors easier.

The time grapher works great and make it easy to regulate you mechanical watchs. Easy intuitive manual setup and operations.

Works great, reasonable price for what you get. Instructions were OK, but could have been better. Once you get the hang of it, it's pretty easy to operate. Color screen is nicer than the monochrome ones, that's the main reason I bought it.
