This 34.5mm. ROLEX ZEPHYR reference 6582 is a very early example, dating to 1957. If I’m not mistaken, I believe it is the FIRST year the design was introduced. You have to love the near pristine quadrant dial with original and unique sword style hands. Look at this 14k. gold bezel-what a great design! The valuable steel riveted bracelet from 1968 will fit up to a 7 inch wrist. Condition is everything-and this watch has been meticulously preserved. I think these vintage dress watches will have “their day” soon!
