Help with code on seconds and Dial on a RPM dashboard

Support
1

Hi , I am working on my second watch face and I am running into trouble with the script to sync the seconds to the turning dial on the RPM meter, the challenge comes from the Dial not being full revolving in a circle but rather says more or less so to the same side of the dail starting at 1 and ending in 16 where the red line beggins, ideally the dial would start at 1 at second one and end up in 16 at second 60 to reset back to 1 at second 00 as shown on the digital dial.

Any help with the script and as an added bonus an explanation on how it works would be appreciated it.

Thank you.

or alternatively (as i was trying to do, a slow pendulum effect where it occilates between the green and the red line is what I was originally working on.

Thanks in advance.
