Looking to trade my Tudor "Big Block" Chrono. This one is a 79170 w/ rotating bezel. 100% original. It just came back from Rolex, but the only thing they ended up doing was authenticating the watch. I had sent it down for a new dial (because the 7 marker had been repaired/reglued long ago), but they no longer have the correct "OysterDate" dial any longer. Presents excellent on wrist. It's running well, keeping time, and all reset to zero. Never been polished, so case is sharp and chamfers present. I would like to stay in the Rolex family for a trade but will listen to all sensible offers. I prefer divers and GMTs. More picts for interested parties.
