This SEIKO 5606-5010 belongs to the popular Lord Matic (LM) collection and stands out for its bold TV-screen style case, giving it a distinctive retro-futuristic appearance characteristic of Japanese watch design in the early 1970s.
Produced in August 1971, it is powered by the Cal.5606A automatic movement with 25 jewels. The movement features hand-winding, hacking seconds, a practical day-date display, and quick-set calendar functions, combining vintage character with excellent everyday usability.
One of the most appealing features of the Ref.5606-5010 is its unusually large and wide case design. Compared with many conventional Japanese dress watches from the same era, its approximately 42mm proportions give the watch a strong wrist presence and make it especially attractive to collectors who prefer larger vintage watches.
The distinctive TV-screen case, classic LM dial design, and versatile Cal.5606A movement make this an interesting example from the golden era of vintage SEIKO.
The watch was serviced in June 2026 and is running properly with a daily rate of approximately +4 to +11 seconds.
