The automatic movement within the 5606 Lord-Matic - like the 1973 Seiko 5606-7230 Lord Matic automatic dress watch here, with Seiko-signed stainless-steel bracelet and original Lord Matic instructions manual - was considered by Seiko to be such an excellent movement it would be subsequently re-worked and placed within Seiko's legendary (and quite accurate) Grand Seiko’s.
The Lord Matic finds its genesis in the Lord Marvel (first made in 1956), with the LM series eventually positioned beneath the King Seiko, but with a very sophisticated new automatic movement and high quality case design and finishing.
By 1968, the LM line had greatly increased in popularity and its movement, the 5606, became one of the most ubiquitous Seiko mechanical movements of the time - the 5606 also formed the basis of higher beat variants fitted to many of the automatic King Seiko and Grand Seiko models of the early to mid 1970’s.
Seiko’s Lord Matic’s were produced at the middle of their lineup, price wise, between 1968 and produced through the 1970’s. Of unique note, not only does the Lord Matic 5606 have a hacking feature, it can be wound via both its automatic movement and by hand. As with all 560x automatic movements, care must be taken not to change the day/date between 9 and 3 o'clock positions, as gear damage may result.
This Seiko 5606 comes on a stainless-steel Seiko bracelet, and with nylon strap, springbar tool, original Seiko Lord Matic instructions manual, and rugged travel case.
