OWT Hands Aid

[LH2Y]

Is it really NOT allowed to use your hands as an aid for OWT?

I just make a circular shape with my left hand and use one of my right fingers to point at a corner in my hand; this corner would be where the number is located in the watch that I saw.

I'm asking for Luxair (DLR), because in the CBT, it says it's not possible to use your hand for ROT, but nothing is mentioned regarding OWT in the instructions page
