1963 Rolex GMT-Master 1675 "Pepsi"

Unveiled in 1955, Rolex introduced the renowned GMT collection to the world. Known famously for its functionality and straightforward aesthetics, the collection was launched with the debut of the 6542 model, the first GMT-Master ever produced.

Over six decades have passed, and the resemblance is uncanny between the design aesthetics of the inaugural model and the contemporary GMT-Master II. Reinterpreting the timeless allure in the context of modern distinctiveness exhibits Rolex's enduring focus on continuity and evolution.

Among the variety of variations that Rolex introduced in the esteemed GMT collection, the GMT Master Model 1675 with Blue & Red Bezel, commonly referred to as "Pepsi," is undoubtedly the piece of significant historical relevance and unsurpassed charm.

This emblematic model, reference 1675, was in production for over two decades, from 1959 until 1980, setting a notable record as one of the lengthiest produced Rolex references in the luxury watchmaker's illustrious history. This long-lasting run not only signifies the model's unprecedented popularity but also reflects its timelessness in terms of design and innovation over the years.

Throughout its production phase, Rolex implemented multiple changes to the GMT-Master 1675 to constantly update and refine its aesthetic and performance aspects. Of these several changes, the transition from gold-plated (“gilt”) dials to matte dials have been the most talked about transformation. The gilt dials, known for their high gloss, gold text, and markers, were in production from the introduction of the 1675 models in 1959 until 1966-67. Later, Rolex transitioned to the matte dials featuring white writing.

Despite these changes, the essential elements of Rolex's design philosophy – the commitment to precision, reliability, and readability – remained constant, making the GMT-Master 1675 an indisputable classic in the horology world. The captivating blend of blue and red on the bezel, symbolic of day and night, has now become the face of the GMT series, creating an ever-lasting legacy.
