Key Features

The Purest Statement of Mid-70s Executive Minimalism (1975): Manufactured in **1975**—a pivotal transitional year during the quartz revolution—the **Seiko Lord Matic** reference **5601-9000** stands out as a rare, highly prized non-date execution within Suwa Seikosha's iconic Lord Matic lineup. Stripped of calendar windows, this reference was designed for discerning collectors who demanded absolute dial symmetry and ultra-clean mechanical elegance.

The Refined 23-Jewel Caliber 5601 Automatic Engine: Powering this historic timepiece is the rare **23-jewel Caliber 5601**, the dedicated non-date variant of the legendary 56-series movement family. Operating at **21,600 vibrations per hour (vph)**, it features **hacking seconds** and hand-winding capability. Free from the delicate plastic quick-set calendar rocker mechanism present in date-equipped 5606 calibers, the 5601 is celebrated for its exceptional long-term mechanical durability and bulletproof reliability.

Architectural ""9000"" Cushion Case and Faceted Aesthetics: Sourced in a solid stainless steel case, the reference **5601-9000** displays strong, broad-shouldered cushion geometry with sharp, faceted lugs. Finished with zero-distortion mirror polishing adhering strictly to Taro Tanaka’s **""Grammar of Design""** philosophy, the ultra-slim profile enables the watch to sit remarkably flat and balanced against the wrist.

Flawless Non-Date Dial Balance with Arabic or Applied Markers: The dial of the **5601-9000** is celebrated for its pristine visual purity and high contrast, often featuring either applied multifaceted hour indices or elegant, highly legible applied/printed Arabic numerals. Without a day or date window interrupting the perimeter, it offers total geometric symmetry, proudly bearing the applied **""LM"" emblem** above 6 o'clock.

An Investment-Grade Classic of Late Mechanical Showa Horology: Produced near the twilight of the mechanical 56-series production run in **1975**, the 5601-9000 is an increasingly scarce and highly sought-after cornerstone profile. Its combination of pure non-date aesthetic symmetry and the robust 5601 caliber makes it an indispensable addition to any curated vintage Seiko collection.
