Tested in Neuchatel 1961, but cased up as a wristwatch a lot later.
Actually there are reports of a serial production Breguet wrist watch and (at least one that i´ve seen) Ulysse Nardin wrist watches fitted with a P260 of those years, but i´m not sure these were available as a "regular model" then. It might be these were fabricated for staff or testing purposes only; not the least because "full-trim" observatory movements, just like F1 engines, don´t go well with daily wear.
The movement was introduced in 1947 for the then new "wrist watch" category of the Observatory trials, which commanded movements not to be larger than 30mm in diameter and 5mm in height (or 707 square mm in volume).
I´m sure these, but also Observatory-trimmed counterparts by Omega, Zenith and Longines, were in use until late 1960´s for chronometric and trial purposes.
As per modern watches, i don´t think there´s another with a P260.
The movements could be found almost always in the past couple of years, so there may be one or more individually fabricated pieces using a vintage movement. At least Christian Pfeiffer-Belli wears one, with a movement finished at a famous watchmaking school in Switzerland.
But i don´t believe there´s been something like a serial production!

Hi Peter,
Interesting to see the GP...never knew about that watch! Thanks!
Did your statement about "full trim observatory movements.....like FI engines...." lend itslef towards the P260 used in Kari's watch? Would this statement just pertain to movements which were created only for the sole purpose of "competition"?
I would hate to see the folks who are purcahsing the observatorie have movement problems. I hear that Kari is replacing parts as needed and really giving these movements the royal treatment.
Happy holidays,

Hi Asg,
I'm pretty sure this movement will last generations - at least if properly treated (but it doesn't need to be pampered).
Nothing in there is specifically fragile - and if a ususal shock protection is added (as in Kari's watches) there's no reason to not be able to stand daily wear. I'd go so far to believe that properly cased this could make an ultimate beater as well - at least almost any automatic movement would be more prone to get damaged (just because of the oscillating mass).
There were certain observatory movements (those which actually were submitted to the trials) with extremely delicate balance pivots for example , but the standard Peseux260 movement balance pvots are 0.1mm which is about a good, reliable standard size.
And as said that's no issue when equipped with shock protection.
All other longevity aspects are pretty much as one could dream of - from my personal view made to last generations.
Besst regards

G'day,
i´ve no idea - and not seen one of Kari´s piece up close so far.
The difference between "race trim" and "civilian" movements is subject of several older discussions and particularly Suitbert is THE instance; thus i´d suggest to have a look at the "fine print" from older posts if that´s interesting for you.
But given it´s not a re-cased historical movement only, i´m somewhat confident Kari included daily wear in his considerations.
Back to X-mas dinner now
Cheers,
Peter
...a shock protection. And as I'm pretty sure Kari hase even lubricated the movement
I'm pretty sure you can get very old without
ever beeing disappointed.
All the best
Suitbert



. 

there is another one equipped with Peseux260. I saved these 2 photos from some website (very sorry that I cannot recall it) a long time ago.

identify what movement (in a UN watch) is in this photo? Is there anything related to what we are talking now Peseux260?

Joe
