- The ref. 1675 succeeded Rolex's original GMT tool watch, the ref. 6542, upon its launch in 1959. Its most distinguishing new characteristic was the inclusion of crown guards, a feature common to Rolex's professional timepieces of the era with one exception—the Daytona. The ref. 1675's case construction differed subtly, with a sturdier, thicker design and an aluminum 24-hour bezel replacing the earlier bakelite version. Early examples bore tells of the model's inception such as a "roulette" date wheel and OCC designation on the dial.

- Presented here is an exceptionally rare example of the venerable GMT-Master ref. 1675 from circa 1960, preserved in outstanding condition. Hailing from the earliest phase of production, its pointed 'El Cornino' crown guards retain their sharp sculptural edges, seldom seen among surviving specimens. Rolex scholars have determined such pointed guards were fitted only on inaugural ref. 1675s, making this example an important document of the model's history.

- The glossy black lacquer dial proves no less alluring, with gilt graphics highly coveted by collectors. While the Swiss T<25 signature indicates the dial surfaced later than its case. The overall effect exudes vintage allure, complementing the watch's early-production rarity.

- For the discerning Rolex collector, opportunities to acquire a GMT-Master blending significance, condition and wearability are exceedingly uncommon. The present example promises to anchor any serious Rolex collection or stand alone as an exceptional daily wearable.
