This is a full-size 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 dial and original hands are virtually pristine. These TUDOR Day-Date watches are becoming quite hard to find-plus, I think are undervalued. Please note-a brand new crystal has been installed AFTER the photos were taken.
