Old-stock unworn ZENITH, it has some traces of 40+ year age, but no wear traces. Gold plating is in perfect condition, original polishing all around. The original movement had intense battery leakage so it has been replaced with a modern substitute (Swiss Ronda movement) which is really good for future reliability, easier battery replacement and warranty.
Slim case (just below 7mm thick), remarkably large size – dimensions 31mm x 38.8mm, strap width is 20mm. It fits really well with perfect time readability on the white classical dial.
