Technical Specifications

Rolex Caliber 3285

Rolex GMT-Master II and the Submarine both showcase remarkable precision and durability but cater to different needs. 

The GMT-Master II is powered by the Caliber 3285 movement, offering approximately 70 hours of power reserve and functions tailored for travelers, such as a 24-hour display and a second time zone with an independently adjustable hour hand. Its bidirectional 24-hour bezel, made from Cerachrom with platinum or gold-coated numerals, enhances its utility for frequent fliers. 

Rolex Caliber 3235 & Caliber 3230

In contrast, the Submariner, driven by the Caliber 3235 or Caliber 3230, also boasts a 70-hour power reserve but focuses on diving functionality with its unidirectional 60-minute bezel, crafted from the same durable Cerachrom material. The Submariner’s superior water resistance of up to 300 meters (compared to the GMT-Master II’s 100 meters) and larger Mercedes-style hands ensure visibility and reliability underwater, making it the preferred choice for divers. 

Both models feature robust Oystersteel cases, scratch-resistant sapphire crystals with Cyclops lenses over the date, and Chromalight displays for excellent legibility in low light. While the GMT-Master II offers a choice between the Oyster and Jubilee bracelets with an Easylink comfort extension, the Submariner comes exclusively with the Oyster bracelet and the secure Glidelock extension system, emphasizing its rugged, dive-ready design. 

In essence, the GMT-Master II excels for global travelers with its dual time zone capability and versatile design, whereas the Submariner stands out for its unparalleled underwater performance and robust construction.

Bezel and Dial

The Rolex GMT-Master II features a bidirectional rotating bezel with a 24-hour scale. This functionality is crucial for displaying a second time zone. The Submariner, designed for diving, has a unidirectional rotating bezel with a 60-minute scale, providing precise measurement of dive times and enhanced safety underwater.

The GMT-Master II’s dial includes a fourth hand to indicate the additional time zone. This hand is distinctively colored to avoid confusion. In contrast, the Submariner has a traditional three-hand configuration, focused on clarity and legibility, essential for divers monitoring their time underwater.

Bracelet and Clasp

The GMT-Master II includes the Easylink 5mm comfort extension link, providing comfort and adaptability for frequent travelers. The Submariner features a robust Glidelock extension system on its bracelet, allowing for easy micro-adjustments without tools. This is ideal for divers who need to fit the watch over a wetsuit.

The GMT-Master II features a more traditional Oysterlock clasp with the Easylink extension, balancing security with everyday wearability. The Submariner, on the other hand, has a Glidelock clasp designed for extreme conditions. It’s secure and adjustable, ensuring it stays in place during diving activities.

Practical Use and Wearability

Comfort and Versatility

The Rolex GMT-Master II is available with either the Oyster or Jubilee bracelet, both known for their comfort and durability. On the other hand, the Submariner comes with the Oyster bracelet, which is robust and comfortable. 

As for versatility, the GMT-Master II comes with a fourth, 24-hour GMT hand, allowing wearers to track two time zones simultaneously. Meanwhile, the Rolex Submariner’s rugged construction and scratch-resistant Cerachrom bezel make it highly durable for various activities, from diving to everyday wear.

Case Size and Weight

The GMT-Master II has a slimmer (12.0mm) and smaller 40mm case size that’s more comfortable for everyday wear. The Submariner has a slightly thicker (12.5mm) and larger 41mm case size due to its enhanced water resistance. 

Despite this difference, both have a similar wrist presence. Their subtle variations cater to different preferences and activities, with neither being overly cumbersome.
