• Pioneer in waterproof technology: Contributed significantly to the development of reliable waterproof watches.
• Iconic design: Recognizable and influential aesthetic that has defined the dive watch category.
• Long and storied history: Continuously evolved and refined over decades, maintaining its core identity.

The Rolex Explorer II: Navigating the Unknown

The Rolex Explorer II, first introduced in 1971, emerged from Rolex's association with exploration in extreme environments, specifically caving and polar expeditions. While also robust and durable, the Explorer II was designed for environments where distinguishing day from night could be challenging – think deep caves or polar regions during extended periods of darkness or daylight. Its signature 24-hour bezel and additional 24-hour hand (GMT function in later models) were crucial tools for explorers navigating such disorienting environments. The Explorer II is built for adventure, albeit a different kind of adventure than underwater exploration.

Key Explorer II Heritage Points:

• Designed for terrestrial exploration: Specifically catered to explorers in caves, polar regions, and other challenging terrains.
• 24-hour functionality: Primary function is to differentiate day and night in environments lacking normal diurnal cycles.
• Rugged and reliable: Built to withstand harsh conditions and provide dependable timekeeping.

Head-to-Head Comparison: Explorer II vs. Submariner

Now, let's delve into a detailed comparison across key aspects to highlight the differences and similarities between the Explorer II and Submariner.

1. Functionality: Dive Watch vs. Explorer's Companion

Submariner: At its core, the Submariner is a dive watch. Its primary function is to measure elapsed time underwater, crucial for safe diving practices. The unidirectional rotating bezel is the key tool here, allowing divers to track their dive time and decompression stops. Its water resistance is paramount, designed to withstand significant pressure at depth.

Explorer II: The Explorer II's defining function is its 24-hour hand and fixed 24-hour bezel. In its original iteration (Reference 1655), this was primarily for distinguishing AM/PM in environments with prolonged daylight or darkness. Later versions, starting with the Reference 16570, incorporated a true GMT function, allowing the wearer to track a second time zone. While robust and water-resistant (though typically less so than the Submariner), it's not primarily designed for diving.

Verdict: If your primary need is a dedicated dive watch with precise elapsed time measurement for underwater activities, the Submariner is the clear winner. If you need to track a second time zone or frequently find yourself in environments where day/night differentiation is important, the Explorer II is more functional.

2. Bezel: Rotating vs. Fixed 24-Hour

Submariner: Features a unidirectional rotating bezel, typically ceramic (Cerachrom in Rolex terminology) in modern models. This bezel is used to measure elapsed time, primarily for diving. The unidirectional rotation is a safety feature, ensuring that if accidentally bumped, it will only underestimate elapsed time, not overestimate it, which could be dangerous for divers.

Explorer II: Employs a fixed 24-hour bezel, usually made of stainless steel. In earlier models, this was used in conjunction with the 24-hour hand to indicate AM/PM. In modern GMT Explorer II models, the bezel works with the independently adjustable 24-hour hand to display a second time zone. It's not designed for timing events in the same way as a dive bezel.

Verdict: The rotating bezel of the Submariner offers immediate, intuitive elapsed time measurement, essential for diving. The fixed 24-hour bezel of the Explorer II provides a constant reference for 24-hour time or a second time zone, depending on the model.

3. Dial and Legibility: Luminosity and Markers

Submariner: Prioritizes maximum legibility, especially in low-light conditions underwater. It features highly luminous hour markers and hands, typically filled with Chromalight (Rolex's proprietary luminescent material) for a long-lasting blue glow. The dial is typically black, providing high contrast against the luminous elements.

Explorer II: Also focuses on legibility, but in potentially different low-light scenarios like caves or dimly lit environments. It also uses highly luminous markers and hands, often Chromalight. Dial colors can vary, with black and white (polar dial) being common, offering different aesthetic options. The 24-hour hand is a distinct visual element on the Explorer II dial.

Verdict: Both excel in legibility. The Submariner's dial is purely functional and focused on underwater visibility. The Explorer II offers slightly more dial variation (especially the polar white dial) while maintaining excellent legibility in various lighting conditions, and the 24-hour hand adds a unique visual characteristic.

4. Case and Size: Dimensions and Presence

Submariner: Historically, the Submariner case size has evolved. Modern Submariners typically feature a 41mm case (previously 40mm), offering a balanced wrist presence. It's designed to be robust and durable, constructed from Oystersteel (Rolex's 904L stainless steel).

Explorer II: Also available in a 42mm case, offering a slightly larger wrist presence than the Submariner. Like the Submariner, it's made from Oystersteel and built for durability. Some might perceive the Explorer II as wearing slightly larger due to its broader bezel and dial.

Verdict: The Explorer II is marginally larger at 42mm compared to the 41mm Submariner, though the difference on the wrist is often subtle. Both are robust and well-proportioned sports watches. Personal preference for size and wrist presence will play a role.

5. Bracelet and Clasp: Comfort and Security

Submariner: Typically comes on an Oyster bracelet, a robust and comfortable three-link bracelet known for its durability and classic Rolex aesthetic. Modern Submariners feature the Glidelock extension system in the clasp, allowing for fine adjustments to the bracelet length, even over a wetsuit.

Explorer II: Also generally fitted with an Oyster bracelet. Modern Explorer II models also incorporate the Easylink comfort extension link in the clasp, providing a quick 5mm adjustment. While not as extensive as the Glidelock, it offers practical on-the-go adjustment.

Verdict: Both utilize the highly regarded Oyster bracelet. The Submariner's Glidelock clasp provides superior adjustability, especially beneficial for divers or those who frequently adjust their bracelet fit. The Explorer II's Easylink offers a simpler, though still useful, adjustment feature.

6. Movement: Caliber and Performance

Submariner: Powered by Rolex's in-house caliber movements. Modern Submariners utilize the Caliber 3235, a cutting-edge automatic movement known for its precision, reliability, and efficiency. It features a Chronergy escapement for improved energy efficiency and a power reserve of approximately 70 hours.

Explorer II: Also equipped with Rolex's in-house caliber movements. Modern Explorer II models use the Caliber 3285, which is very similar to the 3235 but with the added GMT functionality. It shares the same Chronergy escapement, high precision, and approximately 70-hour power reserve.

Verdict: Both utilize state-of-the-art Rolex movements renowned for their performance and robustness. The Caliber 3285 in the Explorer II adds GMT functionality, while the core timekeeping performance is comparable to the Caliber 3235 in the Submariner.

7. Heritage and Purpose: Defining the Roles

Submariner: Embodies the spirit of underwater exploration and adventure. It's the quintessential dive watch, associated with Jacques Cousteau and countless underwater expeditions. Its heritage is deeply rooted in the ocean depths.

Explorer II: Represents exploration in a broader sense, particularly in challenging terrestrial environments. It's linked to caving, polar exploration, and navigating environments where timekeeping and day/night awareness are crucial. Its heritage is tied to land-based adventures and scientific exploration.
