Key Features

Japan's Historic First 10-Beat High-Frequency Triumph (1969): Manufactured in **1969**—a momentous year in horological history defined by technological leaps and mechanical breakthroughs—the **Seiko Lord Marvel 36000** represented Suwa Seikosha's crowning achievement in high-frequency precision. Sourced under reference **5740-8000**, this groundbreaking dress timepiece made history as Japan's very first **10-beat (36,000 vph)** wrist watch, serving as the direct mechanical foundation for later Grand Seiko and King Seiko Hi-Beat references.

The Revolutionary High-Beat 23-Jewel Caliber 5740C Engine: Powering this historic instrument is the legendary **23-jewel Caliber 5740C**, an in-house manual-wind movement operating at a blistering frequency of **36,000 vibrations per hour (10 beats per second)**. By doubling the standard oscillation rate of traditional mid-century movements, the 5740C achieved incredible rotational inertia and chronometric stability, producing an iconic, ultra-smooth sweep second hand motion that captivated watchmakers worldwide.

Architectural ""8000"" Grammar of Design Case Geometry: The reference **5740-8000** is globally distinguished among vintage purists for its strict adherence to Taro Tanaka's **""Grammar of Design""** philosophy. Executed in solid stainless steel (or gold-plated configuration), the case features bold, angular lugs, crisp flat planes, and mirror-polished Zaratsu surfaces engineered to reflect light without distortion, ensuring a flat, comfortable, low-profile fit against the wrist.

Immaculate Non-Date Dial Harmony and Pure Typography: The dial of the **5740-8000** is a masterclass in mid-century visual symmetry and functional restraint, featuring a brilliant sunburst canvas free from date window interruptions. It showcases **hand-applied, multifaceted hour indices** and sharp hands, proudly bearing the applied metal **""SEIKO""** logo alongside printed **""LORD MARVEL""**, **""36000""**, and Suwa Seikosha star emblem typography above 6 o'clock.

An Investment-Grade Milestone of Global Mechanical Heritage: Manufactured during the momentous year of **1969**, the 5740-8000 Lord Marvel 36000 remains one of the most historically significant, universally respected mechanical Seiko references ever produced. Representing the exact historical moment where Suwa Seikosha conquered high-frequency watchmaking right before launching the quartz era, it stands as an eternal, investment-grade cornerstone for serious collectors worldwide.
