The Rolex GMT-Master Reference 1675 "Mark 1 Long E" from 1969 is one of the most highly coveted and collectible variations of the vintage matte-dial GMT-Master lineup. The nickname "Long E" identifies the first version of the matte dials introduced by Rolex to replace the earlier glossy/gilt dials, making it a cornerstone for serious horological collectors.

• The "Long E" Dial Signature: The central bar of the "E" in the word "ROLEX" is elongated, matching the lengths of the top and bottom bars. On subsequent matte dial generations (Mark 2 through Mark 5), this central bar became noticeably shorter.

• Mark 1 Alignment: The vertical alignment of the text is specific to the MK1 production run. The "O" in "ROLEX" aligns perfectly over the "M" in "MASTER". 

• The "Pepsi" Bezel Insert: This reference is paired with the iconic blue and red 24-hour rotatable bezel. Given its age, original inserts often display beautiful, naturally aged fuchsia, pink, or faded pastel tones. 

• Case and Movement: The watch features a 40mm stainless steel case utilizing the robust, chronometer-certified automatic Caliber 1570 movement. It also sports a distinctive plexiglass crystal and a small 24-hour GMT hand.
