The domed acrylic crystal is clear, with no major scratches, cracks, or crazing visible. Movement Inside is the gold-colored automatic Seiko caliber 6206B, a 26-jewel movement.

Remarks The unique day-at-6 layout offers a highly distinctive aesthetic, while the beautifully preserved silver sunburst dial provides excellent visual appeal. The legible dolphin caseback completes this highly charming 1965 Seikomatic. History Introduced in the early 1960s, the Seikomatic line represented Seiko's push toward high-quality automatic timepieces for the everyday professional. The caliber 6206 is particularly notable for introducing a day-date complication to the Seikomatic family, often featuring the day display at the 6 o'clock position. These models are celebrated for their reliable 26-jewel automatic movements and elegant mid-century styling. The distinct dolphin motif on the caseback signifies the original design intent of the watch as a durable, everyday automatic timepiece for the 1960s market.
