économies Rare montre vintage Seiko Lord Marvel haut calibre, haut rythme 36000 5740-8000

Although Seiko was always at the horological forefront it was not the first to get to the ultimate beat rate watch. In 1966 Girard-Perregaux already developed the automatic 32A movement, an upgrade of the manual wind AS 1687/1688, made automatic by the joint effort of watch companies Doxa, Eberhard, Favre-Leuba, Girard-Perregaux and Zodiac.

In 1967 the Lord Marvel 36000 was Seiko's answer to the European enterprise. Seiko used the existing low beat hand-wind 5740B caliber movement that was used in the Seiko Crown 560 (from 1959). This watch was the 36000bph experiment in its purest form.
