Zenith Chronometre Caliber 135-O....Yes the Kari-Voutilainen famous one !

Feb 04, 2024,10:37 AM

I was able to find an old gem recently....the Zenith Chronometre Caliber 135-O....Yes…. the same caliber that won 230 prizes in the Chronometre contests.

Between 1954-64, the caliber was undisputed 'serial winner' in competitions and were regulated by celebrated Chronometers Charles Fleck & Rene Gygax who worked for Zenith at that time.

Zenith used these Observatory movements between 1949-62 after this Zenith used the same caliber but without the Chronometre certification.

This specific example is from Feb 1956 and has been kept (preserved I must say) by the owner in such an amazing condition !

Most vintages from this time aren’t complete but this has all the Chronometer certificates, box and warranty paper. 

oui, even the postal envelope that was stamped in Feb 1956 !

The case is 35mm in steel, astonishingly the timepiece doesn’t feel small and snaps well on the wrist !

and the Chronometre movement…

Special Credits to Nico, who helped me land on this on time.

Have good week ahead !

Killer watch and an amazingly full set! I've started keeping my eye out for these lately, but I doubt I'll be finding one as good as that!

it is a great manually wound chronometer, not too many brands offer one these days.

you should be able to find them, I saw a couple in last weeks on the market. I hope you add one to your collection.

Thank you! I might start looking a little harder

I heard RUMORS that Zenith is going to release a new version of this watch (something less special than the NOS movements finished by KV ones, thank goodness). I hope it's true!

THAT would be great!

A modern steel version of this watch with a new handwind chronometer movement? Sign me up! (I think it would have to be a new movement--as far as I know there's no handwind time-only movement in Zenith's current lineup)

Let's keep fingers crossed.

WOW! That's spectacular!

Really like your 135! For me your version has the most attractive dial. @Nico: If you are aware of another one that is available, please let me know. Mine is a bit older than yours: ...  

Wow, that is stunning!

 By: mahesh : February 4th, 2024-17:48

Another superb one!

Now there's a marvel!
