【Product Description】 The Seikomatic Weekdater (Ref. 6206‑8980) is a mid‑1960s automatic wristwatch that showcases Seiko’s elegant dress‑watch design language in a slim gold‑plated case with a bright silver sunburst dial around 36–37 mm across. Its sunburst silver dial with applied gold‑tone baton indexes, dauphine hands, and a distinctive framed date window at 3 o’clock paired with a full‑spelled weekday display at 6 o’clock gives the watch a refined yet practical presence, while the rounded gold‑plated case and discreet recessed crown keep it comfortable and easy to read in daily wear. 【Historical and Collector Significance】 The 6206‑8980 is powered by Seiko’s 26‑jewel automatic caliber 6206A, a non‑hacking, non‑hand‑winding movement running at 18,000 vibrations per hour, appreciated for its robust construction, smooth winding system, and reliable performance across Seikomatic Weekdater models of the period. As part of the Seikomatic Weekdater line, this reference represents Seiko’s push into higher‑grade automatic watches in the years leading up to Grand Seiko, combining an innovative dual calendar layout, “Water 30 Proof” case construction, and clean mid‑century styling that make it an attractive choice for everyday vintage wear. Well‑preserved 6206‑8980 examples that retain their original silver dial, handset, and Seiko‑signed caseback are increasingly sought after by enthusiasts as characterful 1960s Seiko pieces, offering dependable in‑house mechanics, classic dress‑watch proportions, and a distinctive day‑at‑six layout that stands out in a vintage collection. 【Brand】 Seiko 【Model】 Seikomatic 【Reference Number】 6206-8980 【Serial Number】 4901549 【Movement】 Automatic 【Day Display】 English 【Case Dimensions】 Approx. 37 mm (excluding crown) 【Bracelet Material】 Stainless steel 【Wrist Size Adjustment】 Adjustable from approximately 16 cm to 20 cm by adding or removing links and changing the fine‑adjustment holes on the buckle.
