Tudor 79160 Oysterdate "Big Block" SS Silver Dial

The Tudor 79160 Oysterdate Big Block, introduced circa the early 1980s, occupies a pivotal place in the evolution of chronograph sports watches. Revered among collectors, the "Big Block" moniker refers to its notably thicker case, necessary to house the robust automatic chronograph movement — the Valjoux 7750, a workhorse caliber renowned for its reliability and precision. This reference was the first automatic chronograph in Tudor’s lineup, distinguishing it from its manual-wind Rolex Daytona cousins and signaling Tudor’s technical ambitions. Its stainless steel case is complemented by an integrated tachymeter bezel, screw-down pushers, and a robust Oyster bracelet, embodying durability and a sporty aesthetic. Of note, the silver dial presents sharp contrast with its subdials, offering legibility and vintage charm. The design, featuring date and chronograph functions, marked a watershed for Tudor chronographs, making it a grail reference for fans of 1980s tool watches. With a legacy tightly intertwined with both Tudor and Rolex heritage, the 79160 stands as a significant collectible for those who appreciate mechanical innovation and iconic style. Its rarity and historic significance remain especially prized among connoisseurs seeking early automatic chronograph icons.
