min Hand for mudder Clock from Amazon

I built this Perpetual Calendar Clock using a clockwork from Amazon: https://www.amazon.de/gp/product/B086WDP5ZQ/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&th=1

I found that the minute hand does not fit on the axis of the clockwork I used.
So I reconstructed this with the matching masses.

So you also have a suggestion for a suitable clockwork, since my clock is in operation for a month without problems.
