You would need to replicate the movement first and the OP XXV hasn't been repped, although the PAM Mare Nostrum PAM00300 has been in existence since 2010. The PAM 300 rep does use a good Venus 75 manual wind movement, albeit inaccurate so if that's enough for a first try, hopefully the makers will try to make it. I have seen a quartz version in our local rep market so now it's just the matter of getting the case and the dial colors right.
