Seiko LM 5606-7000 Lord Matic SGP White Sunburst Dial

The Seiko Lord Matic carries a rich history as the successor to the Seikomatic line, continuing the legacy established by the first high beat 36,000 bph Lord Marvel.

First introduced in 1968, the Caliber 5606 became the foundation for the early 1970s King Seiko and Grand Seiko models. This JDM movement features automatic and manual winding, a beat rate of 21,600 bph, and a quickset day-date function with a bilingual English/Kanji day display.

The Lord Matic 5606-7000 proudly showcases Seiko’s Grammar of Design through its distinctive gem-style case, reminiscent of the modern Grand Seiko SBGX253. It captures the elegant design language that made vintage King Seiko and Grand Seiko models so iconic, while offering exceptional value for collectors.

This example features an SGP (solid gold-plated) case paired with a timeless white sunburst dial, beautifully complemented by gold-tone stick indices and dauphine hands. The watch remains in overall good condition, with a clean dial and original crystal. The SGP case shows light signs of wear, including hairline scratches and minor plating loss, while retaining its sharp edges and overall elegant appearance.

A particularly interesting detail is the commemorative engraving on the caseback, which translates to "President of the Japanese National Railways." It was likely presented as a service award to an employee of the Japanese National Railways, adding a unique historical element to the watch.

The movement has been recently serviced with the quickset day and date functions operating normally.

This Seiko Lord Matic 5606-7000 offers a unique opportunity to own a vintage timepiece that embodies Seiko’s celebrated design philosophy, reliable engineering, and a fascinating piece of Japanese history.
