Mesin jam 36.000 bph (beat per hours) high-beat berarti mesin jam yang memiliki 10 hentakan dalam 1 detik (36.000:3.600 detik dalam 1 jam = 10). Maka akan menghasilkan pergerakan yang sangat halus detiknya, seolah-olah tidak terlihat hentakannya. Berikut beberapa produk mesin jam yang tercatat memiliki pergerakan 36.000 bph:
In total there were nine distinct efforts to produce 36,000 vph movements
- The first effort to succeed was Girard Perregaux's effort which brought watches with 36kbph movemetns to market in 1996. A "joint effort" between Eberhard, Favre Leuba, Girard Perregaux and Zodiac purportedly contributed to the devleopment of these watches, or alternatively the automatic winding mechanism of these watches. The movements each manufacturer ultimately came entered the market with were different enough for parts to not interchange between them, so it very unlikely that any of the movements from these watch companies was the product of joint development. This means the first effort really produced 4 distinct movements, and the degree to which there was"joint development" is questionable. Girard Perregaux was not only the first, but was also unique in producing both manual and automatic high frequency movements.
- In 1967 the Longines (cal. 430) "Ultra-Chron" movement appeared.
- In 1968 Seiko (cal. 6145) movement introduced, Favre Leuba introduces cal. FL 1164 (day/date/automatic) based watches, Zodiac introduces cal. 88 (date/automatic) and 86 (day/date/automatic) watches, Movado introduces cal. 405 (day/date/automatice) and cal. 408 (date/automatic) watches.
- In 1969 the Eterna (cal. 2732) movement introduce
- In 1969 the Zenith (cal. 3019) "El Primero" was introduced. It was the first automatic chronograph with an integrated winding mechanism to be produced, and thusly is claimed to be the first automatic chronograph movement ever produced. In 1969, Movado, Zenith and Mondia merged into the MZM Group and Zenith announced the developement of the "first integrated automatic chronograph", hence El Primero (the first in Spanish), in January of 1969.
- In 1969 Movado intrioduced the 405 (day/date/) and 408 (date) watches in their Kingmatic watches.
- In 1970 A. Schild (cal. 1920) was introduced.
- It is not clear when the Felca (cal. 4177) movement was introduced, but it was likely introduced in the 70s. This is one of the few manual hi beat wristwatch movements ever produced.
- In 1975 the Citizen (cal. 7230) movement was introduced.
In the end, then 12 different watchmakers produced watches with high frequency movements of their own design and production: Eberhard, Favre Leuba, Girard Perregaux, Zodiac, Longines, Seiko, Eterna, Movado, Zenith, A. Schild, Felca and lastly Citizen.
