Zenith 2000: Calibre 135 Non-Chronometer

Posted by

We all know the Zenith Calibre 135, a legend among manual chronometer movements!

There were both Zenith- and dual-signed Zenith Favre-Lebua chronometer versions with the Calibre 135. Hard to find one in good condition, if you do, hold on to it!

But even harder to find…

Is the Calibre 135 Non-Chronometer! A paradox, since the chronometer is a more exact movement and considered finer among collectors. But if my understanding is correct, the number of Calibre 135 Non-Chronometer movement is far less than the number of movements Chronometer certified.

The quite anonyme front do not give much away. Typical for it’s time, early-mid 1960’s. Sunburst silver dial, ebony index, sub-seconds.

On the back we find a bit more information, Zenith 2000, waterproof.

The inside on the other hand speaks volume! Beautiful decorated with Geneva bars on the bridges, the big gilt balance wheel, the micro adjustment regulator… The beautiful polished bevels, the big jewles…

Yes, to me, this is a stunning movement!
