Seiko 5 Sportsmatic Ref.6619-8170 Cal.6619A 36.0mm Feb 1966

Fine rays of silver spread across the sunburst dial, lending this Sportsmatic a gentle brilliance that changes with the wrist. Its restrained proportions and uncluttered display capture the easy elegance of 1960s Japanese watchmaking. Behind that calm exterior, an automatic day-date movement brings a pleasing sense of purpose to the design.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Cal.6619A inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
