The first Tudor chronograph was named Oysterdate.
Featuring a manually-wound Valjoux mechanical Calibre 7734, it was introduced in 1970.
Its case dimensions were significant, with a 39 mm diameter more imposing than many standards of the time. The very graphic style of its dial was also unusual.
There were three variations of this first sporty Tudor chronograph, differentiated by their types of bezel:
The second-generation Tudor chronographs appeared in 1971 and remained in the catalogue until 1977.
Nicknamed Tudor “Monte-Carlo” by enthusiasts because their dials are reminiscent of a casino roulette wheel, the 7100 series chronographs retain the case of their predecessors as well as the spirit of their dials with painted hour markers, but their movement is different. In place of the Valjoux Calibre 7734, the Tudor chronographs 7100 series are equipped with the manually-wound Valjoux 234. This new movement offered the wearer better accuracy thanks to a higher frequency – 21,600 beats per hour versus the former 18,000 beats per hour – and had a more sophisticated chronograph mechanism, with a clutch and column wheel.

Tudor Watches was founded in 1926 by Hans Wilsdorf, founder of Rolex and was, as such, a sister company of Rolex. Tudor was meant to offer more affordable watches than Rolex, but with Rolex quality, notably by using Rolex cases and bracelets and off-the-shelf movements. In the 1940s, Tudor released the Oyster. Then in the 1950s Tudor collaborated with the French Navy to produce a diver’s watch, which used the same name “Submariner” as its sister Rolex. Today, the most popular collections are Black Bay and the Pelagos.
