Hi @all, after stumbling across the (newer) JLC Geophysics,

JLC true second.jpg

(picture from C24)


I would like to know more about other pure mechanical-models with true second-function (I am not sure, if this is the only and correct technical term....)
Such a watch might be my next purchase.馃榾

Let麓s go! ::rimshot:: and talk about them......

Seconde Morte -- dead second -- was a hugely valued complication, especially for doctors, that fell out of style when quartz came in and it became a way to distinguish a cheap watch. Rolex did a dead seconds they called a Tru-Beat. A lot had the complication stripped out, but an original today is expensive.

The Geophysic is a great watch by the way, although I prefer the crosshair dial of the 1958 re-issue...

Thank you for the link to the ROLEX: new to me 馃憤

Concerning the re-issue: I don麓t like these hands 馃槈

Searching for true-beat I found this one to add

There were pocket watches and clocks with dead-second movements as well. I have a few "Exact Time" dealer display versions, including the model shown below. While there were issues with most of the wristwatch versions, I have the impression that those employed in high quality larger movements were reliable.
