This vintage Omega Seamaster 166.0213 automatic watch is often affectionately known as the "TV Dial" in watch collecting circles. At its heart is Omega's iconic Cal. 1020 automatic double-calendar movement. It boasts high precision (28,800 vph) and the extremely convenient "independent quick-set day and date" function, making it a leading high-specification movement of its generation. What makes this watch truly remarkable is its 100% authenticity. From the exterior, movement serial number, and strap number to the hands and case back, every component is perfectly period-correct, without any later assembly or modifications. It is an exceptionally well-preserved vintage collector's watch. ~~Service performed in April 2026~~ 【Brand Series】Omega / Seamaster 【Official Model】166.0213 【Year of Production】Approximately 1981 (Movement serial number 45,xxx,xxx) 【Core Movement】Cal. 1020 automatic movement 【Case Material】Stainless steel, original Ω-marked crown 【Case Diameter】35*40mm (excluding crown), original crystal with Ω mark 【Dial Design】Elegant silver-white 【Bracelet】Original integrated steel bracelet, original buckle, can be worn up to 18 inches 【Product Condition】Timekeeping/functions are normal, serviced in April 2026 【Functions】Automatic + manual.
