Can I bring a phone watch in the hard pen calligraphy exam?

After thinking about it for a long time, I think it should be ok.

Hard pen calligraphy test should be the same as painting. It takes effort. Generally speaking, it is not allowed to bring mobile phones and watches, for fear of cheating in passing answers. How to cheat in hard pen calligraphy? Can you also send an abcd?

So I think it should be possible.
