In 1970, Tudor debuted its first manual-wind chronograph - the illustrious Oysterdate ref. 7031/0. Clad in vivid hues with distinctive pentagonal hour markers, the watch immediately captivated aficionados. Its imposing 39mm case featured sculpted lugs and muscular lines unlike the more modest proportions of the era. The graphic dial, bold and unusual, was a daring gambit that proved immensely successful, earning enthusiastic acclaim.
The inaugural release comprised three sporty chronograph variations, each endowed with a unique bezel - the present example displays a black plexiglass insert. Their sophisticated yet athletic aesthetic spoke of refinement and vigor in equal measure. Identical dials combined cool grey, inky black registers, and a crisp white minute track. Unconventional luminous pentagon hour markers earned the "Home Plate" nickname among collectors for their resemblance to a baseball field. A final flourish was the uncommon 45-minute chronograph counter. Secured within 50-meter waterproof Rolex Oyster cases and screw-down crowns.
Highly sought after today, this example houses a manual-wind Valjoux 7734 movement with over 45 hours of reserve power. The caseback denotes "Original Oyster Case by Rolex Geneva" affirming its provenance. Preserved in outstanding condition, this cherished vintage chronograph is a treasure for discerning collectors who appreciate horological icons.
