1973 Rolex GMT-Master Ref. 1675 'Root Beer' MK2 'Non-Serif' matte 'Nipple' dial

The GMT-Master reference 1675/3 marked Rolex’s first attempt at adding a dash of gold to its professional travel watch. Introduced in the late 1960s as a two-tone evolution of the iconic 1675, this model combined the rugged utility of a pilot’s tool with the warmth and elegance of 18k yellow gold. With its distinctive bi-metal construction, the 1675/3 became a symbol of both technical capability and refined taste, a watch equally suited to long-haul flights and long lunches in the city. Retaining the caliber 1575 and all the hallmark features of the GMT line, it brought a softer, richer aesthetic to the cockpit.

 

No version better exemplifies that blend than the early matte brown dial variants of the 1970s. These dials, with their warm chocolate tones and soft, velvety finish, offered a more understated look compared to the glossy dials that came later. Most notable are the applied hour markers—small, raised, cone-shaped indices in gold with luminous centers—affectionately dubbed “nipple” markers by collectors due to their distinctive shape. The combination of that unusual dial furniture with the warm brown and gold tones, especially paired with the bi-color bezel insert, gave this version of the GMT-Master a unique character. The insert itself, blending rich brown with golden tones, quickly earned the nickname “Root Beer” for its uncanny resemblance to the fizzy American soft drink — a playful moniker that stuck and became part of the model’s lore.

The example offered here is a Rolex GMT-Master Ref. 1675/3 ‘Root Beer’ with MK 2 ‘Non-Serif’ matte ‘Nipple’ dial which dates to 1973.

 

The period correct, brown, grainy matte MK2 ‘Non-Serif’ dial remains in excellent condition with no visible wear, featuring a vibrant brown hue when exposed to sunlight. The ‘Nipple’ hour markers present a charming and warm patina hue which matches perfectly with that on the original golden hands.

 

The stainless steel case remains thick, still showing factory standards like the prominent lug bevels. It shows normal wear signs. The case back remains in the same condition. The 18k yellow gold bezel has aged featuring a lovely rosy patina. The original insert has partially faded adding more character to the watch.

 

The original acrylic crystal has some minor marks that could be easily buffed away if wanted.

 

It is running strong and keeping excellent time as it was fully serviced recently.

 

It comes suited on its Rolex Oyster 7836 folded-links stainless steel and yellow gold bracelet with 280 end links and clasp code 14 that shows normal wear and stretch for its age.

 

This one also hides a final surprise: serial 3x44444—a lucky streak of repeating 4s that collectors won’t overlook.
