In 1970, Tudor released its first chronograph - the Oysterdate - with a manual Valjoux movement 7734. The third series, reference 94210, was introduced in 1976 and was the brand’s first automatic chronograph wristwatch. The 94210 model is dubbed by watch collectors as "Big Block" due to the shape of the case. The present watch features a black dial and bezel, posing a distinctive color contrast with the orange chronograph hand and indexes. Adding an element of intrigue, this model features screw-down pushers similar to the Rolex 6263 and 6265 Daytona models.
