Battery consumption / optimization of binary watch face

Hi there,

I use Tag expressions in WFS to create a binary watch face.
I have 5 elypsis for the hours (0 to 23) and 6 for the minutes (0 - 59).
E.g. for the 32s of hours I have the opacity (0 to 100) calculated as: floor([HOURS_0_23]/32)%2*100

This works fine but it seems to be quite heavy on the battery… (My watch face is mainly black, I doubt that it is too bright)
I own and use a Galaxy Watch 6

Any suggestions how to have the same outcome with lower battery consumption?

Kind regards
Lukas
