With Patek Philippe Extract from the Archives confirming production of the present watch with stainless steel bracelet in 1957 and its subsequent sale on June 10th of 1959.
To the best of our knowledge this watch has never before been offered in public.
Reference 3418 was introduced into the market in 1958, the same year as the calibre 12'''400 movement. This ingenious model was designed to allow the easy change of the leather strap for a metal version by unscrewing a metal ring fixed onto the case back and revealing the lugs, hence its designation "convertible".
