The SH4130 is that bad, huh? Makes sense - DD>SH definitely seems true for other movements as well.Cf and btf > zf simply due to movement, DD4130 is not the same as SH4130
I'm torn between CF w/ deep crystal and BTF. I saw a reddit comment mention some people sell the CF dial on RWI, but I can't find where. Is that a thing? Best option might be buying a BTF and then purchasing a CF dial.
