Tudor Oysterdate Big Block Silver Dial 79160

Categories: Starter Watches, Tudor, Watches

The Tudor Oysterdate Chronograph ‘Big Block’ Reference 79160 with its classic silver dial is a landmark piece in horological history, revered by collectors as the brand’s first-ever automatic chronograph and a foundational “neo-vintage” icon . This 40mm stainless steel timepiece, produced from the late 1980s into the mid-1990s, derives its enduring nickname “Big Block” from its thicker, more robust Oyster case, a necessary innovation to house the legendary Valjoux 7750 automatic movement — a workhorse caliber celebrated for its reliability and precision that powered the watch’s chronograph and date functions .

The watch presents a striking and highly legible silver sunburst dial, which features sharp contrasting black subsidiary registers in a classic ‘reverse panda’ layout . Applied steel hour markers and luminous hands, which often develop a charming patina over time, ensure optimal readability . The case is complemented by an integrated steel tachymeter bezel, robust screw-down pushers, and a screw-down crown, emphasizing its purpose as a durable tool watch while offering a sporty yet sophisticated aesthetic . The dial is thoughtfully marked with “OYSTERDATE” and “AUTOMATIC – CHRONO TIME,” and is protected by a domed acrylic or sapphire crystal depending on the specific production year .

Presented on its original, heavy-duty stainless steel Oyster bracelet, secured by a folding clasp often signed by Rolex or Tudor, the 79160 perfectly embodies the robust design language of its era . As a significant precursor to the modern Tudor Heritage Chronograph and a contemporary of the Rolex Daytona, the Big Block 79160 holds a pivotal place in watch collecting. Its unique combination of pioneering mechanical innovation, distinctive vintage styling, and robust everyday wearability makes it a grail reference for connoisseurs who appreciate early automatic chronographs and the rich, intertwined heritage of Tudor and Rolex .

 Trustindex verifies that the original source of the review is Google. I worked with Josh after being referred to him by a friend and he was incredibly responsive.  He called me on a Saturday within minutes of me sending him a text.  He was patient in answering all of my questions and sourced an unworn Rolex watch I wanted within 24 hours.  Josh and Wolvyn are the best!
