BLNR Origins and Nicknames: The term BLNR, derived from “bleu noir” (Blue Black), perfectly encapsulates the essence of the blue and black bezels on the ref. 116710BLNR and ref. 126710BLNR. These bezels, crafted from Rolex’s Cerachrom, signify a groundbreaking achievement in combining zirconia and a blue pigment for a durable, scratch-resistant, and fade-resistant ceramic alloy. The introduction of the BLNR bezel marked a significant moment in 2013, showcasing a world-first in creating a two-color combination on a single-piece ceramic component.
Design Comparison: 116710BLNR vs. 126710BLNR: Case: While both models feature 40mm stainless steel cases with black dials and blue and black Cerachrom bezels, the GMT-Master II 126710BLNR subtly refines the lugs for a more polished appearance. The re-shaped lugs, though minimal, contribute to an overall heightened aesthetic refinement. The cases maintain the “super case” classification, exhibiting a noticeable thickness compared to earlier GMT-Master references.
Bracelet: The standout update with the GMT-Master II 126710BLNR is the introduction of the Jubilee bracelet, offering a dressier alternative to the Oyster bracelet found on the 116710BLNR. The Jubilee’s five-link curvy design contrasts with the Oyster’s flat three-link structure. Initially exclusive to the Jubilee, fake Rolex expanded choices in 2021, allowing the 126710BLNR to also sport the Oyster bracelet.
Dial Signature: While the dials remain nearly identical, the 126710BLNR introduces a minor update below the 6 o’clock position. A small crown insignia now graces the dial between the words “Swiss” and “Made,” enhancing the subtle details of the latest iteration.
Movement Comparison: 116710BLNR vs. 126710BLNR: The evolution extends to the movement, where the 126710BLNR houses the Rolex Caliber 3285, a successor to the Caliber 3186 within the 116710BLNR. The new movement boasts a longer power reserve of 70 hours, a notable improvement over the 48-hour reserve of its predecessor. Additionally, the Caliber 3285 incorporates Rolex’s Paraflex shock absorbers, enhancing impact resistance.
Price Comparison: 116710BLNR vs. 126710BLNR: While the retail price of a GMT-Master II 126710BLNR with an Oyster bracelet is $9,500, the Jubilee bracelet variant is priced at $9,700. However, the secondary market dynamics significantly impact the pricing. Pre-owned 126710BLNR models start at nearly $20,000, a testament to their desirability. On the other hand, the discontinued 116710BLNR is available in the pre-owned market starting at around $16,500.
Choosing Your GMT-Master II: In the realm of BLNR GMT-Master II watches, the choice between the 116710BLNR and 126710BLNR is nuanced. Both models excel in timekeeping precision, GMT functionality, and iconic design. The decision hinges on individual preferences, whether drawn to the refined aesthetics of the updated case, the versatility of bracelet options, or the enhanced movement specifications.
Rolex GMT-Master II 116710BLNR and 126710BLNR represent not just watches but coveted symbols within the world of luxury timepieces. Whether you gravitate towards the timeless allure of the original or embrace the subtle refinements of the latest iteration, the allure of the Batman endures, transcending generations and trends.
