The Rolex GMT-Master II, a watch synonymous with global travel and aviation heritage, boasts a complex and highly reliable movement that is the subject of much admiration and scrutiny. This review will delve into the intricacies of the Rolex GMT movement, examining its evolution, its key features, and comparing it across various models. We will also touch upon related topics such as the differences between the GMT-Master and GMT-Master II, bezel variations, case sizes, and the iconic Pepsi and BLNR variations.
Rolex GMT Master II BLNR Specifications: A Starting Point
Before embarking on a broader discussion, let's ground ourselves in the specifics of a popular model: the Rolex GMT-Master II BLNR (Batman), reference 116710BLNR. This model, with its striking blue and black Cerachrom bezel, exemplifies the contemporary evolution of the GMT movement.
* Reference: 116710BLNR
* Case: Oyster, 40mm, 904L steel
* Bezel: Bidirectional rotatable 24-hour graduated bezel. Two-colour blue and black Cerachrom insert.
* Movement: Caliber 3186 (we'll explore this in detail later)
This seemingly simple specification list hides a world of horological engineering. The 40mm Oyster case, crafted from corrosion-resistant 904L steel, provides robust protection for the sophisticated mechanism within. The bidirectional rotating bezel, a hallmark of the GMT-Master, allows for the tracking of a second time zone independently of the main timekeeping hands. The Cerachrom insert, made from a virtually scratch-proof ceramic, ensures lasting durability and vibrant color. But the true heart of the watch lies in the Caliber 3186 movement.
Rolex GMT Master 2 Movement: The Caliber 3186 and its Predecessors
The Rolex GMT-Master II BLNR, as well as many other modern GMT-Master II models, utilizes the Caliber 3186 movement. This is a self-winding mechanical movement, meaning it automatically winds itself through the movement of the wearer's wrist. It's a highly evolved mechanism, building upon the legacy of previous GMT movements.
The Caliber 3186 is a significant step forward in Rolex's GMT technology. It offers:
* High Precision: Thanks to its meticulous design and construction, the 3186 boasts exceptional timekeeping accuracy, within the COSC (Contrôle Officiel Suisse des Chronomètres) certified standards.
* Power Reserve: A substantial power reserve of approximately 48 hours ensures the watch continues to run even if it's not worn for a couple of days.
* Independent Hour Hand: The key feature of any GMT movement is the independently adjustable hour hand. This allows the wearer to set a second time zone, making it ideal for travelers who need to keep track of multiple time zones simultaneously. The 24-hour graduated bezel complements this function perfectly.
