The Rolex GMT-Master II "Batman" – the reference 116710BLNR and its successor, the 126710BLNR – has quickly become a grail watch for many collectors. Its striking blue and black Cerachrom bezel, coupled with Rolex's legendary reliability and prestige, makes it a highly sought-after timepiece. However, understanding the production history of these models, and pinpointing the exact production date of a specific watch, requires navigating a complex system of serial numbers and Rolex's often opaque production records. This article delves into the fascinating history of the BLNR, exploring the timeline of its production and providing guidance on how to determine a specific watch's age using various resources, including Rolex production date charts and serial number databases.
A Timeline of the "Batman": From Concept to Current Production
The story of the BLNR begins long before its official release. Rolex's GMT-Master line has a rich history, born from the needs of pilots and international travelers. The introduction of the Cerachrom bezel, a significant technological advancement in ceramic bezel technology, marked a turning point. This incredibly durable and scratch-resistant material would become a defining feature of many modern Rolex models.
2005: The Dawn of Cerachrom
The year 2005 is crucial in understanding the lineage of the BLNR. While the 116710BLNR itself wasn't unveiled yet, this year saw Rolex announce a new generation of GMT-Master II watches featuring the groundbreaking Cerachrom bezel. This innovation laid the groundwork for the future "Batman." Earlier GMT-Master IIs used aluminum bezels, which were susceptible to fading and scratching. The introduction of Cerachrom signaled a commitment to enhanced durability and aesthetic longevity.
2013: The Batman Emerges
Finally, in 2013, Rolex unveiled the reference 116710BLNR, instantly capturing the attention of watch enthusiasts worldwide. This model, nicknamed the "Batman" due to its two-toned blue and black bezel, represented a bold departure from the traditional Pepsi (red and blue) and Coke (red and black) bezel variations. The combination of the robust Cerachrom bezel and the instantly recognizable color scheme proved to be a winning formula. This marked a significant shift in the popularity of the GMT-Master II, solidifying its position as a highly desirable sports watch. The 116710BLNR quickly gained a strong following and became notoriously difficult to obtain through authorized retailers.
2019: The Next Generation – 126710BLNR
Rolex, ever-innovative, didn't rest on its laurels. In 2019, the brand introduced the reference 126710BLNR. This updated version features the Caliber 3285 movement, a significant improvement over the Caliber 3186 found in the 116710BLNR. The Caliber 3285 boasts improved chronometric performance, a longer power reserve, and enhanced shock resistance. While visually similar to its predecessor, the subtle design refinements and the upgraded movement solidified the 126710BLNR's position as a superior timepiece. The updated model also continues to be highly sought after, though the wait times for authorized retailers remain substantial.
