Just wanted to say the P2002 and P2003 movements are very accurate and well regulated. Mine runs about +/- 2 seconds over several days and I saw similar performance other 233 owners.
I really don't think you can go wrong with either one.
I hope more 270 and 289 owners will chime in. However, unlike the 233, it does not appear there are that many 270 and 289 in the market at the moment.
Again, good luck in your search.
