The Rolex GMT-Master II is a legend, a watch synonymous with travel, adventure, and unparalleled horological excellence. Within the GMT-Master II family, the "BLNR" – a moniker derived from the French "bleu noir" (blue black) – holds a particularly coveted place. This article will dissect the differences and similarities between two iterations of this iconic timepiece: the Rolex 116710BLNR and its successor, the Rolex 126710BLNR, offering a comprehensive comparison to help you navigate the complexities of choosing between these two exceptional watches.
Understanding the "BLNR" Designation:
Before delving into the specifics of each model, it's crucial to understand the significance of the "BLNR" designation. This refers to the striking bi-color ceramic bezel insert, a hallmark feature of both watches. This bezel, crafted from Rolex's proprietary Cerachrom ceramic alloy, boasts exceptional scratch resistance and vibrant color saturation. The deep blue and black segments are perfectly delineated, creating a visually captivating and highly legible time display. This ceramic bezel is a significant upgrade over the aluminum bezels found on earlier GMT-Master II models, offering superior durability and longevity.
Rolex 116710BLNR: The Precursor
The Rolex 116710BLNR, released in 2013, was a game-changer. It marked a significant evolution in the GMT-Master II line, introducing the highly sought-after Cerachrom blue and black bezel. Prior to its release, the GMT-Master II was primarily associated with the classic "Pepsi" (red and blue) and "Coke" (red and black) bezel variations. The 116710BLNR brought a fresh, modern aesthetic to the collection, instantly capturing the attention of collectors and enthusiasts alike.
Key Features of the 116710BLNR:
* Caliber 3186 Movement: This self-winding mechanical movement is a workhorse, known for its accuracy, reliability, and impressive power reserve of approximately 48 hours. It features a Parachrom hairspring, resistant to shocks and temperature variations, ensuring consistent timekeeping performance.
* Oyster Case: The robust Oyster case, with its screw-down crown and caseback, provides exceptional water resistance (up to 100 meters). This ensures the watch can withstand the rigors of daily wear and even more demanding activities.
* Oyster Bracelet: The watch is typically fitted with a comfortable and durable Oyster bracelet, featuring solid links and a secure clasp.
* GMT Function: The bidirectional rotating bezel allows for the tracking of a second time zone, a key feature of the GMT-Master II. The independently adjustable hour hand allows for quick and easy time setting adjustments.
Rolex 126710BLNR: The Refinement
The Rolex 126710BLNR, introduced in 2019, represents a significant upgrade over its predecessor. While retaining the iconic design, it incorporates several subtle yet impactful improvements.
