The main reason I want one is not to adjust the watches accuracy myself, but to mesure SPD loss of my watches with no running seconds.
Yes, for the typical hobbyist these are sufficient.
Bought the Weishi 1K a couple of years back. It's a very useful device and a must have if you're intending to elevate the hobby to another phase (i.e. DYI repairs, modding etc.). But do beware of the pitfalls it may bring about. For some time, I had to shelf it all up as the want for accuracy and efficiency was starting to become a "must have" to a point that it hinders my overall enjoyment of my timepieces. When that "must have" fantasy subsided and I in turn, started to understand the behavior and tolerances of my watches, Its now an ever-available tool for me to assess the ranges of watchnut concerns from the usual minor issues such as lets say, magnetism as well indicators for the "big ones" or the inevitable service/maintenance. Good luck.
Yup. I have the 1900 and love it.
IIRC, the 1000 can detect the rate but can't determine amplitude of a co-ax.
I bought one
Bought one recently on Amazon by some Chinese brand called OTOOLWORLD. Cost $189 and is pretty amusing to use.
I agree. If you are not a watch maker and just want it for fun and knowing when your watches need to be services the Weishi 1000 is perfect and fairly inexpensive.
A Timegrapher is of value even if you have no intention to ever open your watch. With one you'll know the health of your watch and be able to read signs that tell you it's time for a service.
