the only BP reps that are valid are the 16600 and the 16613 (they are both the best OOTB).
avoid BP for the 6 digit stuff
That's a bit of an overstatement. I have a number of BP watches that are quite nice. Some that easily rival the more expensive ARF or Noob offerings, often at a substantial savings. BP daydates are arguably the best available in both 36 and 41mm size. The day fonts are much better than Noob. And nobody comes close to BPs full gold wrapped bracelets.
BP Datejust ‐ $238, couldn't be happier with it. Completely stock.
BP Daydate 36mm - $358, one of my fav's
BP Miyota Hulk $368, best Hulk rep dial ever made
BP Explorer I - $348, hands down best ETA version
BP Explorer II - $278, nobody make these anymore
BP FG Sub - $378 recent V2 release. Outstanding watch for the price
And vintage GMTs? OMG bro NOBODY touches BP! I'd be here all day posting shots!
