Zenith 135 chronometer, screwed steel case, from early 60ies, top-condition!
Zenith 135 steel chronometer-watch with the classic silvered dial in all original condition. This movement is one of the most famous and aesthetic movements ever built. Only around 10000 were produced by Zenith in the 50ies and early 60ies, but many were not fitted into cases. The whole watch is in a stunning condition. Sought after screw-case!! Perfect dial, signed crown. Movement in top condition, no scratches. Just serviced. This model of Zenith 135 with the screw case „Zenith 2000“ was the last series of this movement in the early 60ies!
With cut bimetallic compensation balance, blued steel Breguet balance spring and cam-type patented regulator. Besides its large size and general high quality of design and execution, there seems to be at least a couple of notable features to this movement. Of particular interest is the distinctive arrangement of the gear train wherein the minute wheel is placed off-center, thus allowing exceptionally large balance and barrel, manual wind.
An icon of watchmaking history!!
