Well. 3 so far:
Rep Seamaster Bond -> gen
Rep Aquaracer chrono -> gen
Rep 16710 GMT Master II -> gen
Next is probably the Steelfish (if I find a good deal).
I would never buy a gen Sub because unlike the fantastic 3185 (which no rep can ever duplicate), the basic 3135 movement isn't anything special. It's a robust, great movement of course but functionally it's just like basic ETA. And besides, the WM9 rep is too good... at least for someone who isn't overly obsessive. However, that same argument could be used with the SFSO, but it's only a $1.4 watch preowned.
And as much as I love the classic Sub SFSO is my favorite diver watch. It's just so perfect in every way.
To answer the question: Yes... reps have been a "gate drug" to gens. But unlike what happens to most people... after buying gens I started to appreciate the reps even more. The best ones are fine watches and wearing rep or gen... doesn't make any difference to me.
