The brand
Introducing Seiko would be useless, it is the most important manufacturer in the world. Founded 120 years ago, it really begun to be a leader in the 60’s/70’s thanks to their automatic watches and of course with their quartz models.
Seiko invented many concepts (analogic and LCD quartz, Kinetic watches, Spring Drive, etc) and marketed all sorts of designs. Its range of watches is incredibly wide, answering almost all budget, design or quality questions.
The range
Sportsmatic is an entry level automatic watches range introduced by Seiko in the early 60’s. Entry level won’t mean that these watches were of low quality, some of them were even very well built compared to models from other manufacturers.
The first Sportmatics were time only (Seikosha 2451 movement) or date only watches (Seikosha 820 movement). In 1963-1964, Seiko marketed its first day/date calibre, the Seikosha 410 and fitted it in the first Seiko 5 Sportsmatic. These first “5” had a chromed case (the latter ones had a stainless steel case) and no date quickset.
In 1964, Seiko launched the 5 Sportsmatic Deluxe, which was an enhanced version of the 5 Sportsmatic. All the Deluxe had a stainless steel case and a dedicated pusher to set the date. At that time, Seiko modified its way to name their movements and adopted a 4-digit naming convention.
From 1964 to 1967-68, Seiko produced quite a lot of Sportsmatic models and we can sum up the production like this :
- Sportsmatic “time-only”, 6601 movement (ex 2451)
- Sportsmatic Calendar 820, 7625 movement (ex 820)
- Sportsmatic Deluxe, 7605 movement
- 5 Sportsmatic, 6619 movement (ex 410)
- 5 Sportsmatic Deluxe, 7606 and 7619 movement
Some models were unusual, for example the Sportsmatic “SilverWave”, water resistant with a screwed crown.
The very last Sportsmatics only had their name engraved on the case back, with a 7625 calibre (1968).
