The Seiko 5600 Lord-Matic automatic movement - like the one within the all original 1976 5601-9000 LM here - was considered by Seiko to be such an excellent movement that the company re-worked it and placed them within their 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 5600, became one of the most ubiquitous Seiko mechanical movements of the time - the 5600 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 procuced through the 1970’s. Uniquely, not only does the Lord Matic 5600 movement have a hacking feature, it can be wound via both its automatic movement and by hand.
This Seiko 5600 comes with its original stainless steel bracelet, nylon NATO strap, springbar tool, and Pelican travel case.
