Rolex GMT-Master

Rolex is one of the most recognized watch manufacturers in the world, based in Geneva, Switzerland. The brand has been producing watches since the early 1900s and built its reputation on reliability, durability, and consistency. Rolex watches are made to high standards of finishing and precision, and the brand has a strong track record of holding and often increasing value over time. They are widely collected and traded in the secondary market, which gives buyers a reasonable degree of liquidity compared to most other watch brands.

The GMT-Master was introduced in 1954 in collaboration with Pan American World Airways, designed for pilots and crew who needed to track two time zones simultaneously. The reference 1675 was produced from 1959 through 1980, making it one of the longer-running references in Rolex history. It featured the caliber 1570 movement, a reliable and well-regarded automatic movement that was a staple in Rolex sports models during that era. The 1675 is best known for its distinctive two-color bezel insert, most commonly in the red and blue "Pepsi" configuration, and its 40mm case size, which has aged well and remains a comfortable fit by modern standards.

Among collectors, the 1675 is a well-established reference with a broad following. Vintage examples from the 1960s and 1970s attract attention for their original dials, aged patina, and period-correct components. Originality is a key factor in valuing these watches, as the collector market places a significant premium on unmodified examples with matching parts. The reference sits in a sweet spot where it is old enough to carry genuine vintage character but was produced in sufficient numbers that examples do appear on the market with some regularity.

Key Details To Consider

This is a Rolex GMT-Master reference 1675 from 1970, identified by its 2.4 million serial number, in good used condition with a strong, well-preserved overall presentation. The case was recently professionally polished by a certified Rolex polisher, and the lugs remain sharp with clean beveling that holds up to Rolex standards. All case numbers are fully visible and intact.

The dial is the correct MK1 long E variant, showing an even yellow patina across the plots and matching hands. This kind of consistent, natural aging is exactly what collectors look for in a vintage piece like this, and it gives the watch a character that is difficult to replicate. The original red back Pepsi bezel insert has aged and faded naturally over the decades, taking on a softer, more muted tone that adds a lot of personality to the watch.

The bracelet is the period-correct Oyster style, retains all its original links, and shows very little stretch, which is a notable plus for a watch of this age.

The movement was professionally serviced in August 2026 and has been pressure tested to 3ATM (30 meters). It runs properly and has been well looked after.

The watch comes with its original box and the original punched and stamped papers, making this a complete set. For a 1675 of this vintage, having matching documentation and box alongside such a well-preserved, all-original example is a genuine find.
