Case and Crystal The 36 mm stainless steel case showcases the sharp geometric lines and brushed surfaces that defined Seiko's "Grammar of Design" philosophy in the 1970s.

The bracelet is currently sized to fit a wrist of approximately 17.5 cm and integrates seamlessly with the lug design. Condition This timepiece is in stunning vintage condition. The dial is pristine with no visible spotting or patina. The faceted crystal is remarkably clear, showing only some wear, which is a rare find for this specific reference.

It is a rare opportunity to acquire a piece of this design pedigree in such well-preserved condition. History Introduced in the late 1960s, the Lord Matic (LM) line was positioned as a high-quality mid-tier offering, sitting just below King Seiko and Grand Seiko in the brand's hierarchy. It was instrumental in solidifying Seiko's reputation for automated precision and avant-garde design during the 1970s. The 5606 caliber used in this series is widely respected by watchmakers for its slim profile and engineering excellence, representing a high point in mass-produced mechanical watchmaking. / Second Vintage SKU: SEI-SLJ-0073
