Horological Meandering

For some reason I have gotten bitten by the frenetic sound and the romantic promise of high frequency watches - i.e. those beating faster than 28.800 vph. I started my journey in the topic with my Eterna Sevenday Fastbeat, which got joined by the Grand Se...  

I guess we should define high-beat ourselves, or should we use the Mfr's terminology? You are calling watches that are faster than 28,800 High Beat, yet Seiko used the term Hi-Beat quite loosely in some instances, when they moved from 21,600 to 28,800. I ...  

Rolex did use an El Primero but in a de-tuned, 28,800 vph version. And yes, I am talking about faster than 28,800 Seiko was not the only one to use the term in this way, JLC for instance did, too

One of the first was the 1935 introduction by Minerva of a 360,000 A/h movement, Calibre number 42. This allowed the sweep second hand to complete one sweep each second with 1/100 second precision. (from watch-wiki.net ) This will make an impressive l... 

But it's still in prototype stage, like the new Zenith Defy Lab, IIRC. Thanks a lot! Added the Longines in the meantime and the Minerva will follow 👍🏻

The AP is the Jules Audemars Chronometer with AP escapement. I found the Buren Calibre 82 (5 Hz) Best wishes Alkiro

Do you know of any others, too? You seem to shoot such things from the hip

All very different and based on AS cal's, as also used with FL & Eberharfor. The UN was based on ETA as your Eterna. Piaget & Movado also did high beats - but not sure if in house. Citizen & Orient too - a Seiko link? Felca also had a standalo...  

Will add them. Movado was El Primero, IIRC? And three wonderful specimen you have! 👌🏻

Seems that the 3019 was EP, the 405 and 408 were not

Added a couple in the meantime

El Primero cal 40.0 Clive New in 1989 ...  

The logo sure looks like the 90's logo (note the slight difference with the logo on the example I posted, which also has a Zenith 40.0), but I didn't think the chronograph came with the wave bracelet after 1986, when the 1911 bracelet came out. I'm always... 

30, 32, 42.1, 42.4, 440, Ernest Borel had a high beat offering in the 70s too?

From Breguet and Seiko... ETA to follow

include members of the Communaute de Precision Horlogere, formed in 1957 at the promotion of Charles Blum of Ebel. They worked together with A. Schild to develop a 5-Hz version of those ebauches (also, I believe, an automatic winder for it). Gerard-Perreg...  

Glad for all this additional information - will add it to the post above ASAP! The beauty of Puristspro, I guess - the learning never ends

I did indeed find an example of an Ebel FastBeat with the caliber 215, which is the high-beat version of the AS1687: This was in an auction ad. The Fast Beat also came with the AS 1920, which was only supplied as a 5-Hz movement. We also know it as the Gi...  

Have added the Mido, the GPs I did not have and the others that were new. 👍🏻 Thank you so much! If you come across any others...

But for quite some not yet sure, where they got cased in

- 430: central seconds - 431: central seconds, date - 432: time only - 433: small seconds - 6952: date - 6972: day date

It's the "Seiko SUS Military" released in 1996. With a 25 jewel 4S15 movement operating at 28,800 vph based on a King Seiko movement from the 1970s. There were two versions, a black dial (SCFF001) and a silver dial (SCFF003). I understand that 'SUS' stand...  

This includes Seiko and JLC amongst others. Your SUS was part of the return of high end mechanical movements for Seiko in the 1990s and I believe the 4S15 movement was a modern version of the 52 series of movements from the 1970s. And the watch is definit... 

I searched for many years as well... found this one in December 2003 in a small second used watch shop under the tracks in Ueno, Tokyo... I just happened to be wearing it this weekend. Thanks for the additional information ; )
