{"product_id":"1970s-bulova-oceanographer-serviced","title":"1970s Bulova Oceanographer (serviced)","description":"\u003cp\u003eA handsome late-1970s Bulova Oceanographer with plenty of character. Dating to 1978, this example pairs a finely textured black dial with gold-tone markers, a matching case and a day-date display at three o’clock. The warm red-brown leather strap adds to its distinctly ’70s appeal. Inside is Bulova’s automatic calibre 1133.10, based on the ETA 2879 and operating at 21,600 beats per hour. The movement was fully serviced in August 2026 and has been calibrated to run between approximately +3 and −3 seconds per day on a timegrapher at the time of testing. The case, crystal and dial show some age and wear consistent with a vintage watch. \u003c\/p\u003e\n\u003cp\u003eMaker: Bulova\u003cbr\u003eModel: Oceanographer Dual-Day\u003cbr\u003eDate Code: N8\u003cbr\u003eYear of Production: 1978\u003cbr\u003eMovement: Automatic\u003cbr\u003eCalibre: Bulova 1133.10, based on ETA 2879\u003cbr\u003eFrequency: 21,600 bph\u003cbr\u003eCase Diameter: 36.1mm\u003cbr\u003eCase Thickness: 12.3mm\u003cbr\u003eLug-to-Lug: 41mm\u003cbr\u003eLug Width: 18mm\u003cbr\u003eBracelet\/Strap: Leather\u003cbr\u003eService History: Serviced August 2026\u003cbr\u003eAccuracy at Testing: Approximately +3\/−3 seconds per day\u003cbr\u003eWarranty: One-year mechanical warranty\u003c\/p\u003e\n\u003cp\u003eThe “333 Feet” designation is the watch’s original depth rating.
