When one brings up high quality vintage Seiko, Grand Seiko and King Seiko are almost always the first to come, due to high finishing standard and technological development – however, the first Seiko with a high-beat mechanical movement was housed in neither of these two lines, but rather the Lord Marvel 36000 – like this full serviced Seiko 5740-8000 example here, with Arabic dial – during the 1960s.


During the 1960s era, most mechanical movements operated at 18,000 beats per hour (bph).   As usual, the Swiss watchmaking world sought to dominate this field, but shortly after their first entry – the Girard Perregaux in 1966.


In response, Seiko launched its manual winding caliber 5740C in 1967, which became the first Japanese 36,000 bph movement, and second in the world. Of interesting note, the 5740C was the precursor to the caliber 44 used inside the King Seiko Chronometer.


Seiko would manufacture the Lord Marvel 5740 from 1967 and 1975, and the high beat 5740C – like the one here – is considered to be the 3rd generation Lord Marvel model and represents the peak of the line.


As noted by Worn & Wound, “[The 5740-8000 Lord Marvel] is a quintessential dress watch, with clean lines, understated elegance, and of course a beautiful and technologically advanced in-house manual wind movement.”


This Lord Marvel 36000 comes with a leather strap, nylon ZULU strap, hard plastic travel case, and springbar tool.
