I have way too many automatic and manual wind watches, and now I know a LOT more about how all of them run. This tool works very well and is easy to learn. Watches can be held in more than enough orientations to full understand their timekeeping capabilities. It's been a lot of fun, as I slowly work through the process of regulation the watches as far as I am capable. Read more

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. Read more

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. Read more
