Seiko Seikomatic 6206-8010 Weekdater Kanji Day Black Sunburst Dial

For sale the Seiko Seikomatic Weekdater 6206-8010, a collectible vintage timepiece from 1965 that perfectly showcases Seiko’s mid-century design prowess and mechanical innovation.

The watch features a well-proportioned 37mm stainless steel case with a classic, elegant profile and a recessed crown at the 4 o'clock position. The standout of this piece is its black sunburst dial, which is relatively rare for this era. It is beautifully complemented by applied silver-tone indices, sleek dauphine hands, and the signature "Weekdater" layout featuring a date window at 3 o'clock and a distinct full-display Kanji day wheel positioned at 6 o'clock.

Powered by the robust Seiko Caliber 6206 automatic movement, this watch offers smooth, reliable daily performance and represents a key era in Seiko's transition toward high-end automatic calibers.

This example from 1965 remains in very good condition. The stainless steel case has been professionally polished while carefully retaining its sharp factory edges. It boasts an overall clean dial, and the crystal shows only minimal light hairline scratches. Importantly for collectors, the iconic engraved Dolphin logo on the caseback remains visible.

A brilliant representation of 1960s Japanese horology, the 6206-8010 combines unique dial symmetry with enduring mechanical quality, making it a fantastic addition to any vintage collection.
