The problem with the review at repgeek is, that it comes to the wrong conclusion.
I had both + a gen dial from watchco.australia and I can say,
the better version is definitly NOT the Silix VCO, but the Josh/Trusty version.
File datewindow to a trapezoid shape,
get the cross from the Silix Vacs006 VC (an old 37mm version)
and you have the best you will find.
