This is a Rolex GMT-Master II, reference 16710, often nicknamed the “Pepsi” because of its iconic red and blue bezel insert.

• Case: Stainless steel Oyster case, approx. 40mm diameter. The sides of the case show visible wear and scratches from regular use, giving it a tool-watch character. The drilled lug holes indicate it is an earlier production model (common in late 1980s through early 2000s).

• Bezel: Bi-directional rotating bezel fitted with the red and blue aluminum insert, designed for tracking a second time zone. The insert shows typical signs of age and wear, which is consistent with vintage pieces of this era.

• Dial: Black “Swiss-T<25” dial with luminous hour markers and Mercedes hands. The GMT hand features a red shaft with a luminous triangle tip for 24-hour tracking. The cyclops lens magnifies the date at 3 o’clock.

• Crown: Signed Rolex Twinlock crown with protective crown guards.

• Bracelet: Stainless steel Oyster bracelet with the Rolex coronet clasp. The clasp and links show wear and scratches, suggesting it has seen regular use.

• Movement: Automatic Rolex Caliber 3185 (or possibly 3186 in later production years), a COSC-certified chronometer movement with independent quickset GMT hand, allowing multiple time zone tracking.

• Era & Markings: The case and bracelet wear are consistent with a piece produced and worn in the late 1980s through the 1990s.

Overall Impression

The Rolex GMT-Master II 16710 Pepsi is a highly collectible model, valued for its history, functionality, and classic design. While this example shows visible scratches and wear, collectors often prize these signs of authenticity. A professional polish and service could restore much of its original luster, but some enthusiasts prefer the natural “worn” patina.

This particular watch carries the hallmarks of a true tool watch—one that has traveled and lived, which fits perfectly with the GMT’s heritage as a pilot’s and traveler’s companion.
