Key Features

The Sovereign Peak of 1964 Suwa Manual-Wind Luxury (1964): Manufactured in **1964**—the momentous historic year of the Tokyo Olympics that placed Japanese micro-engineering on the world stage—the **Seiko Lord Marvel** represented Suwa Seikosha's preeminent high-end dress watch line prior to the widespread expansion of Grand Seiko. Sourced under reference **5740-1990**, this iconic 5740-series reference served as the direct technological bridge between early luxury dress timepieces and Seiko's historic 36,000 VPH high-beat innovations.

The Over-Engineered 23-Jewel Caliber 5740 Manual Heart: Powering this historic timepiece is the revered **23-jewel Caliber 5740A**, an in-house hand-wound engine operating at a classic frequency of **18,000 vibrations per hour (vph)**. Celebrated by vintage purists for its high-grade movement construction, this movement utilized a lavish **23-jewel specification** to minimize gear-train pivot friction, combining exceptional daily stability with Seiko's proven **Diashock** anti-shock mechanism and smooth manual winding.

Architectural ""1990"" Classic Dress Case Geometry: The reference **5740-1990** is globally distinguished among vintage collectors for its timeless, mid-century dress case proportions. Featuring clean, sweeping lugs with sharp polished bevels, the low center-of-gravity case architecture sits remarkably flat against the wrist, sliding effortlessly under a tailored executive shirt cuff.

Immaculate Non-Date Dial Balance and Cursive Typography: The dial of the **5740-1990** is a masterclass in mid-century visual restraint and symmetrical harmony. Free from calendar clutter, it displays a radiant silver sunburst canvas decorated with **hand-applied, multifaceted rectangular hour indices**—with a prominent double index at 12 o'clock—and razor-sharp dauphine hands. It proudly features the legendary applied or printed cursive **""Seiko Lord Marvel""** typography above 6 o'clock.

An Investment-Grade Cornerstone of Suwa's Horological Legacy: Manufactured in the milestone mechanical year of **1964**, the 5740-1990 23-jewel Lord Marvel remains an extraordinarily coveted, universally respected reference for serious vintage Seiko collectors worldwide. It captures the exact historical moment where Suwa Seikosha perfected non-date manual-wind dress elegance right before introducing the 36,000 VPH Lord Marvel 36000. Built to an uncompromising heirloom standard, it stands as an eternal testament to 1960s Japanese watchmaking excellence.
