The Tudor Oyster Unicorn is actually a very uncommon variety. This is a fairly large watch, measuring 34mm. with an all-dial appearance, making it look larger. The dial and hands are original and VERY clean. Notice the 12,3,6,9 ROLEX EXPLORER type configuration. The gold plated case with steel back looks amazing and has a nostalgic 1956 inscription on the rear. The original very uncommon OYSTER PATENT crown is still installed. The fine manual winding TUDOR movement was just cleaned and is shimmering and accurate. These movements were on a par with the ROLEX manual winding movements from the same era. This is a highly collectible vintage TUDOR.
