The SEIKO Sportsmatic Five 6619-8030 is an antique watch with automatic winding and day-date functions, one of the earliest models of the Seiko "Five" series, which debuted in the 1960s and became a global sensation. Historically, this model was released during the transition from the Sportsmatic series to the Seiko Five series. The Sportsmatic series was developed by Seiko with the aim of popularizing automatic watches. The "Sportsmatic 5” a derivative of the series, was named "Five" for its five functions: shock resistance, water resistance, date display, day of the week display, and automatic winding. Technological innovations include the adoption of Seiko's proprietary "Magic Lever" automatic winding mechanism, which reduced the number of parts, improving reliability and mass production. The integrated receiver plate increased assembly efficiency and allowed for lower prices. It was a huge hit in the market immediately after its release in 1963, and exports expanded dramatically from 1965 onward. In 1966, its sales surpassed the total production of automatic watches in Switzerland. The Sportsmatic Five 6619-8990 is an antique model close to the origins of the Seiko 5 and played a key role in supporting the spread of Japanese-made automatic watches in the 1960s. For detailed technical information on the caliber 6619A 21 Jewel, it is Seiko's automatic signature movement, introduced in the 1960s. It was used in the Seiko 5 and the Sportsmatic Week Date, making it a reliable and highly serviceable practical watch. Its distinctive features, such as the Magic Lever automatic winding, day-date function, and quick-set date, contributed to the spread of Japanese-made watches at the time. For this reason, it continues to attract many vintage collectors today.

■Condition: There are scratches on the case, case back and the Crystal Domed Acrylic has lots of fine scratches visible to the naked eyes due to long-term use.

The watch is in good condition overall since quick-day-set device still does work precisely. The date advances via pushing the crown (quick-set). But Day-of-week requires to be first set by rotating the hands 24 hours then correct time be adjusted. Very careful handling, when set the time/date, is required due real vintage watch.

It won’t match modern wristwatches for convenience, but it doesn’t need to: its strength lies in its history, elegance, and the spirit of mid-60s watchmaking.
