Seiko Lord Matic 風凪 (Kazunagi) 5606-7070 (1970)

Presented for auction by Second Vintage This Seiko Lord Matic reference 5606-7070 is an exceptional example of Japanese watchmaking from the early 1970s, representing the sweet spot between the standard Seiko lineup and the higher-end King Seiko and Grand Seiko models. Produced in March 1970, this timepiece showcases the "Grammar of Design" case architecture with sharp facets and clean lines that defined the era. With its highly desirable "Water Proof" caseback marking—a detail that was phased out shortly after this production year—and a pristine dial, this Lord Matic offers a sophisticated blend of history and style for the discerning collector. Brand: Seiko Model: Lord Matic Reference Number: 5606-7070 Serial Number: 033390 Movement: Automatic Caliber 5606 Dial: Silver sunburst Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Near-mint vintage condition with timegrapher readings showing approximately +27 to +34 seconds per day, which indicates a healthy movement. Dial and Hands The silver sunburst dial is preserved in outstanding condition, free from staining or patina, retaining a bright and metallic sheen. It features applied baton indices with black central inlays that match the slender stick hands, ensuring high legibility. The applied "SEIKO" and "LM" logos are crisp and raised, adding depth to the watch face. A framed day and date window is positioned at 3 o'clock, featuring a bilingual English and Kanji day wheel. The text at the bottom remains sharp and unblemished, contributing to the watch's fresh appearance. Case and Crystal The stainless steel case measures 37mm and presents a sharp, unpolished aesthetic with well-defined lines typical of Tanaka's design philosophy. The bezel is polished, contrasting beautifully with the brushed upper surfaces of the lugs. The unique "Open Thru Glass" case construction, noted on the caseback, indicates a front-loading design that enhances water resistance and structural integrity. The crystal is clear and free of significant marks, allowing for an unobstructed view of the dial. The caseback engraving is remarkably deep and legible, clearly displaying the "Water Proof" designation and serial numbers. Movement Inside beats the reliable Seiko Caliber 5606, a 23-jewel automatic movement that was a high-grade workhorse of the era. This movement offers both hand-winding and hacking capabilities. The watch is currently running within vintage tolerances, with timegrapher readings showing approximately +27 to +34 seconds per day, which indicates a healthy movement. Strap The watch is fitted with a deep brown leather strap featuring a crocodile grain pattern. It pairs elegantly with the stainless steel case and is finished with a silver-tone buckle, making it ready to wear immediately. Condition This timepiece is rated in near-mint condition. The dial is flawless to the naked eye, and the case edges remain factory-sharp with only the faintest signs of handling. The preservation of the caseback engravings is particularly noteworthy, suggesting the watch saw very little use over its lifetime. Dimensions With a diameter of 37mm excluding the crown, the watch sits prominently yet comfortably on the wrist, offering a modern presence despite its vintage origin. The lug width accommodates standard straps, allowing for easy customization. Remarks The Lord Matic 5606-7070 is often cited as one of the best value propositions in vintage Seiko collecting due to its high-quality movement and superior case finishing. Finding an example in this state of preservation, particularly with the 1970 specific "Water Proof" caseback, is becoming increasingly difficult. History Introduced in 1968, the Lord Matic line was positioned just below King Seiko in the hierarchy, offering high-beat movements and sophisticated designs to the upwardly mobile Japanese public. The 5606 movement became legendary for its reliability and slim profile, allowing for the elegant case shapes that have made these watches timeless classics today. /Second Vintage SKU: SEI-SLJ-0057
