Move it to the wrist you use most
If you are right handed try it on your right wrist for a few days and see if it winds better. Or your beer glass lifting hand.

I don‘t think that the malfunction depends on the daily activities of the wearer.
The movement of the 15400 is inside my ROO 15707 CE (four years old, serviced by AP in Nov. 2018) as well. In February this year - after days full of activities - it stopped working only about half an hour after I had laid the watch down for the night. Th...
Frequet serving needed
The movement might look robust, oil sinks are very small and can not apply sufficient oil in jewels for 3120&3126 and so frequent servicing will be necessary to sustain watch functions and parts quality are also not that good according to my local repaire...
