Produced during the early 1990s, this 40mm stainless steel model is often referred to as a “Big Block” due to its thicker case design, a result of housing one of the earliest automatic chronograph movements. The striking silver dial, paired with contrasting chronograph registers and a date display at 3 o’clock, delivers a timeless look that reflects Tudor’s close historical connection to Rolex sports watches.\u003c\/p\u003e\n\u003cp\u003eHighly regarded by collectors, the 79170 offers vintage charm, everyday wearability, and an important place in Tudor’s chronograph history. Features such as the rotating 12-hour bezel, Oyster-style case construction, and period-correct details make it a standout example from an era when Tudor shared many design elements with its famous sister brand. Whether added to a growing collection or worn as a distinctive daily chronograph, the Prince Oysterdate 79170 remains a sought-after classic with enduring appeal.\u003c\/p\u003e\n\u003cp tabindex=\"0\"\u003e\u003cstrong\u003eReference Number:\u003c\/strong\u003e\u003cspan\u003e M79170\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e\u003cspan\u003e 40mm in stainless steel\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eBezel\u003c\/strong\u003e: Bidirectional Rotating aluminum insert \u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eSunburst silver with black subdials\u003cstrong\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eDomed Acrylic\u003cbr\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003cspan\u003e  \u003c\/span\u003e\u003c\/strong\u003eETA Valjoux Calibre 7750\u003cbr\u003e\n\u003cul\u003e\n\u003cli data-start=\"518\" data-end=\"664\"\u003eAutomatic, self-winding movement\u003c\/li\u003e\n\u003cli data-start=\"518\" data-end=\"664\"\u003e45 hour power reserve\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"518\" data-end=\"664\"\u003eQuickset date \u003c\/li\u003e\n\u003cli data-start=\"518\" data-end=\"664\"\u003eChronograph function\u003c\/li\u003e\n\u003cli data-start=\"518\" data-end=\"664\"\u003eCOSC Certified\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e30 meters\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet\u003c\/strong\u003e: Stainless steel with folding clasp \u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox and Papers:\u003c\/strong\u003e\u003cspan\u003e Includes box and undated papers, as well as service papers dated July 2016.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Pre-Owned Tudor","offers":[{"title":"Default Title","offer_id":44423366508586,"sku":"10-20-36502","price":7900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/5686\/5316\/files\/P6050215.jpg?v=1780686241","url":"https:\/\/www.manfredijewels.com\/products\/tudor-oysterdate-big-block","provider":"Manfredi Jewels","version":"1.0","type":"link"}
