Finding an example with such a pristine dial and well-preserved case is becoming increasingly difficult, making this a prime opportunity to acquire a historically significant and highly wearable vintage Japanese timepiece. History Introduced in 1967, the Seiko Lord Marvel 36000 (reference 5740C) was a monumental achievement for the Japanese watchmaker, serving as their very first 36,000 bph hi-beat watch. It paved the way for the legendary high-frequency movements later found in the prestigious Grand Seiko and King Seiko lines. The Lord Marvel line itself was originally positioned as Seiko's premier luxury offering before the introduction of Grand Seiko, and the addition of the hi-beat movement in its final iteration cemented its legacy as a true horological milestone.
