This collectable Tudor "Big Block" Chronograph sports the cool bi-directional 12 hour bezel for a second-zone! The large 40mm case was surely the inspiration for the Heritage Black Bay models whilst the silver Panda dial oozes vintage Daytona chic. Water-proof thanks to Rolex's legendary construction and fitted to the correct Oyster bracelet (date stamped for 1986) this 94210 is powered by the valjoux 7750 automatic chronograph movement (beating the first automatic Daytona by some margin!) and covered by our 2 year warranty.
