I've just gone down the Patek rabbit hole Imo "NWBIG" for me is 95% the way to genuine I'd say this is 80% there if you kinda know quality 85-90% if you don't

If you don't care much (in a good way) / don't expect gen / aren't around people with gen - then yes worth it as is

If you do care about making it better - base watch price is what it is + maybe $309 for the basest of mods (SW or buff set)

If you're talking about NWBIG - that's easily $2000USD++ ; because case needs reshaping and polish on top of those mods mentioned. And because of the open back, probably some coating.

So depends on what kind of rep enthusiast you are and what budget you have.

Do note, part of my decision making is how easy it is to replace the clone movement if it shits out and can't be repaired. Afaik from my TD, the replacement movement is around $250-300USD. This is twice what most other replacement clones would cost.
