Rolex Red Submariner 1680 & Explorer II 1655 Pair

The GMT-Master reference 1675 is a significant model in the brand's history, representing an evolution from earlier GMT-Master references. It was produced for an extended period, allowing for numerous dial, bezel, and hand variations throughout its production run. This reference is notable for its introduction of crown guards, enhancing the watch's robustness and contributing to its distinct profile. It solidified the GMT-Master's design language, which would influence subsequent generations.

This reference features a 40mm case, available in stainless steel, yellow gold, or a two-tone combination of steel and yellow gold. It is powered by the automatic Caliber 1575, a chronometer-certified movement known for its reliability and a power reserve of approximately 42 hours. The watch is fitted with an acrylic crystal and offers a water resistance of 50 meters, suitable for everyday wear. The bidirectional rotating bezel, typically with an aluminum insert, displays a 24-hour scale.

For collectors, the 1675 is highly sought after due to its long production period and the resulting variety of configurations, including different dial types (gilt, matte), hand styles, and bezel colors (Pepsi, all-red, all-black). Its four-digit reference number and acrylic crystal are key characteristics that define it as a vintage Rolex. The reference appeals to those interested in the historical development of the GMT-Master line and the nuances of vintage watch collecting.

The Rolex Submariner reference 1680 is notable as the first Submariner model to feature a date complication, marking a significant evolution for the line. Introduced in the late 1960s, it bridged the gap between the earlier no-date Submariners and later iterations, offering enhanced functionality while retaining the robust characteristics of the professional tool watch. This reference is distinguished by its single cyclops date magnifier on the crystal, a feature that would become a hallmark of many subsequent Rolex models.

This reference typically features a 40mm steel case, housing the self-winding Caliber 1575 movement. The movement provides a power reserve of approximately 48 hours. The crystal is acrylic, commonly referred to as Plexiglas, contributing to its vintage aesthetic. Water resistance for the 1680 is rated at 200 meters, consistent with its design as a reliable underwater instrument.

For collectors, the reference 1680 is highly sought after, particularly early examples with "Red Submariner" dials where the word "Submariner" is printed in red. These variants represent a distinct period in Rolex's production history and are prized for their rarity and aesthetic appeal. The 1680 appeals to those who appreciate the blend of historical significance, functional design, and the tangible qualities of vintage Rolex manufacturing.

The Rolex Explorer II reference 1655, often recognized by its distinctive orange 24-hour hand, was introduced as a tool watch for speleologists and polar explorers. It offered enhanced legibility in low-light conditions and a fixed 24-hour bezel to distinguish between AM and PM in environments where day and night cycles are obscured. This model stands apart from its GMT-Master sibling by focusing on a specific utility rather than multiple time zones, making it a specialized instrument within the Rolex professional line.

This reference features a 39 mm stainless steel case, housing the automatic Caliber 1575 movement. The movement provides a power reserve of approximately 42 hours. A robust acrylic crystal protects the black dial, which is characterized by its luminous hour markers and the prominent orange 24-hour hand. The watch is water-resistant to 100 meters, suitable for its intended robust use.

Collectors value the 1655 for its unique aesthetic and its position as the original Explorer II. Its fixed bezel and distinctive hand set differentiate it from later Explorer II iterations and other Rolex sports models. The reference appeals to those who appreciate purpose-built watches and the early design language of Rolex's professional series, representing a specific chapter in the brand's history.
