If I have made the changes personally, and you need some tools but they are not very expensive and with a little patience everything will be perfect,
And if of course when you like, we can talk about any change you want to make to your skx007, the best crystals, ceramics, etc.
In my second Seiko project I also plan to change everything mentioned plus the caliber from a 7s26 to a 4R36.
I have also gotten my hands on several Rolex OQ, Date Day, and sub., GP, Cartier, AP, and a few more, for hands and dial changes.
In this wonderful world of watches there are always interesting things that can be improved
