# Exceptional Zenith automatic Respirator - 1966 # ¤ shiny stainless steel case ¤ ~ rare and magnificent green dial~ One of the major problems of watch brands in the 50s and 60s was the waterproofness of the cases. In 1964, Zénith tried to develop a case that had the particularity of having a movable base which, with the pressure in case of underwater launch, would sink towards the cap and reinforce the water-resistance of the watch. This movement is reminiscent of the lung and this is why was called respirator. - stainless steel case in excellent condition - automatic movement Zenith 2552 pc of excellent quality, 25 jewels, 21600 vph - stainless steel back numbered 292e696 - green dial with patina and gold edge, very good condition - golden appliquéd markers - perfectly functional instant calendar, window at 4:30 - beautiful golden baton hands. - perfectly smooth and functional Zenith crown - new plexi screen with its new gasket (ordered from distributor Zenith in Switzerland) - 30 x 30 mm excluding crown, 20 mm between the lugs - green genuine ostrich Zenith strap with its unroc Swiss made buckle with a Zenith logo, like new, value of €200! - insured and registered shipping via Colissimo The movement is clean and works perfectly, oiled and adjusted.
