Who is familiar with the 868/1 movement details?

Hello all - I am the proud owner of an MUT QP which houses the 868 movement. I'm trying to dial in the settings on my watch winder for the most efficient winding of this watch, and am looking for some additional info from the movement guru's out there.

Specifically, does the 868 wind bidirectionally, or only in one direction, and if so, which direction (clockwise or counterclockwise)? I think it is a counter-clockwise wind only, but strangely the manual and JLC website don't confirm this.

Thank you all!
