SWANSOFT Timegrapher No.1000, Multifunctional Watch Tester, Watch Timing Machine for Watchmaker, Watch Calibration Tool for Mechanical Watches

Functions as expected; easy to use; average Chinese manual. The 12 v power adapter and on/off switch are in-line. Kinda messy; would have preferred a wall wart with the on/off switch on the main unit.Very nicely made. For example, brass inserts are used for all screws. The watch stand is very nice.I have no way to check the frequency accuracy but there is almost no drift between a Baume & Mercier that shows 0 s/d drift and a cheap DDS signal generator.If you have an oscilloscope, you can observe the microphone output by connecting a probe to the pad marked 'A' and the probe ground to the pad marked 'GND' on the printed circuit board. I soldered pins to these pads and leave the back cover off.

Easy to set up; works well. I wish the instructions explained the data gathered more thoroughly.

Showed up very quickly. Works well straight out of the box.

This is a very well-made watch timer. I would have given it 5 stars in all categories except that the watch holder does not do well with the typical large watches of today such as Seiko 5 Automatics, Tags, Rolex Submariners and other diver type watches. When you rotate the watch face down it will likely fall out so you have to be very careful to have it sitting on something soft. Also the watch holder has an inconvenient stop that only allows 180 degree rotation of the face (around the direction of the watchband). You can also rotate the entire mechanism which in theory should work okay but this stops you from tracking the watch time with a 45 degree downward angle unless you mount the watch upside down which won't pick up the ticks in many cases. However, it is possible to work around these problems so its still a good value at this price but it would be REALLY nice if they allowed the holder to rotate 270 degrees like higher-priced systems.

Works as advertised, so I can regulate movements, before continuing my watch construction.

Works great. Still figuring out the data.

The users manual lite on depth. Pick up some books and or research, learn the knowledge's, needed.

Works amazing! A must have for all mechanical watch enthusiasts! Ordered it and in less than 24hrs it was at my door and I was regulating watch movements!
