    Great price, just delivery was slower than I expected. The device is easy to set up, easy to read and a great value for watch lovers. Let you know the condition of your mechanical watch movement in minutes.

    Very useful tool, it has helped me repair many watches that need timekeeping. Very accurate.Put my Armitron watch on the perfect time, -1 second per day. The factory setting is almost +44 seconds per day, which is better than the factory setting. Anyone serious about mechanical watches should have this tool.

    For someone like me (not a watchmaker) who is only interested in how a watch works and its precision, this machine is almost perfect and well made. The only problem is the almost useless manual (at least for me). I hope it contains some technical information to help the user understand the readings he is getting.

    This tool is not only a must-have tool for professionals to adjust watches and even some smlaa clocks. Watch collectors deserve it too, in just a few minutes you'll read and understand what the watch is telling you. Don't think the phone app will do this. No training or software required.

    Great tool, very easy to set up and use. The product is well made, runs smoothly, effortlessly, and appears to be of high quality. I'm a beginner in watchmaking and have been reading about using a timer. Weishi seems to be the go-to brand used by most of the hobbyists and experts I follow.
