This is a full-sized 36mm Tudor Oyster Prince Day-Date having an automatic Tudor movement with day-of-the-week and date feature, just like the Rolex president. Notice the steel crenelated bezel and very clean Rolex Oyster case with Rolex Oyster winding crown, all very clean and unpolished. The original dial and hands are virtually pristine. These Tudor Day-Date watches are becoming quite hard to find – plus, I think they are undervalued. Please note, a brand new crystal has been installed after the photos were taken.
