Rolex produced a limited series of dials in the early 1960s featuring an elusive "exclamation" mark, a unique characteristic found on this particular timepiece. According to scholars, this mark signifies a transitional phase when Rolex reduced the radium content on the dials. Due to their short production span, dials with the "exclamation" mark, such as the one on this watch, are exceptionally rare. Notable features include a small luminous red hand for the second time zone indicator and 'Cornino' pointed crown guards, typical of early models.

This vintage GMT-Master has been meticulously preserved for over six decades. Its exceptional case condition, highlighted by broad factory bevels on the lugs, is a detail highly sought after by collectors. Paired with the original Rolex Japan certificate, SCOC certificate, and presentation box, this timepiece is further distinguished by Its dazzling glossy gilt dial, embellished with uniformly aged luminous plots that harmonize with the patina on the hands, showcases a lovely yellow hue, further enhancing the watch's vintage charm and desirability among collectors.
