There are two versions of this watch. The original version contains errors in the instructions and articles. The second version is fairly easy to assemble. The box does not indicate which version is inside. The cover of the user manual says "LK501-V2". But don't expect it to work very well. There is a lot of friction and misaligned parts that prevent it from running for more than a minute. But it's still interesting to collect and find out how the clock goes. So I recommend buying them. Just don't expect to use it as a running watch.
