This serviced Rare Vintage 1970 Seiko Lord Matic LM 23 Jewels Ref. 5606-7140 is a spectacular example of early-1970s Japanese horology, embodying the bold design language and mechanical sophistication of Seiko's executive dress watch lineup from the era. It is driven by the highly regarded 23-jewel Caliber 5606 automatic movement, a high-grade workhorse engineered with a slim profile, hacking mechanism, and manual winding capability to deliver the robust mechanical longevity and precision that defined the Lord Matic legacy. Following a full mechanical service, the caliber operates with optimal efficiency, providing seamless automatic performance, smooth hand-winding, and flawless day/date quickset functionality that established the line's prestige.
The face of the watch features a striking, professionally refinished vibrant blue dial with a refined subtle vertical brush texture that captures light with sharp precision across its surface. A crisp day-date window sits at 3 o'clock, featuring a classic dual-language display that highlights the textbook 1970s geometric symmetry of the layout. The dial is beautifully appointed with an applied silver SEIKO logo, applied LM emblem, crisp Lord Matic typography with the Suwa factory insignia, applied faceted baton hour markers with a prominent double index at 12 o'clock, and matching slender hands, adding incredible depth, legibility, and captivating visual flair to the rich blue background.
The stainless steel case is beautifully preserved, retaining its sharp factory geometry, polished bezel, and distinctive fluid cushion contours that sit comfortably and ergonomically on the wrist. Maintaining its classic executive identity, this reference positions its crown at 3 o'clock, perfectly complementing the balanced proportions of the case. Outside of the expertly restored blue dial, the timepiece remains entirely authentic and complete, retaining its original factory movement, hands, crystal, case, crown, and rare original stainless steel Lord Matic multi-link bracelet to meet the strict standards of discerning enthusiasts.
Collectors fiercely pursue the vintage Lord Matic series for its high-grade 56-series architecture, ergonomic cushion case geometry, and quintessential early-1970s styling. While purists value untouched factory dials, this expertly refinished specimen complete on its authentic bracelet combines classic 1970s engineering with an eye-catching, distinctive color profile, a refined and essential cornerstone ready for any serious vintage Seiko collection.
