The Rolex GMT-Master II reference 126710BLNR-0002, popularly known as the Batgirl, is a professional travel watch featuring a 40mm Oystersteel case and an iconic bidirectional rotatable bezel with a two-color black and blue Cerachrom ceramic insert. Designed for durability and legibility, the timepiece utilizes a black dial with a Chromalight display, featuring large hour markers and hands filled with long-lasting luminescent material. This specific model is distinguished by its five-link Jubilee bracelet, which includes a folding Oysterlock safety clasp and the Easylink 5mm comfort extension link for easy adjustments.
Technically, the watch is powered by the in-house caliber 3285, a self-winding mechanical movement that offers a power reserve of approximately 70 hours and a precision of -2/+2 seconds per day. Its primary complication is the GMT function, which uses a dedicated 24-hour hand and a graduated bezel to track multiple time zones simultaneously. The local hour hand can be adjusted independently in one-hour increments without stopping the movement, making it highly practical for international travelers. Additionally, the watch features an instantaneous date at the 3 o’clock position under a Cyclops magnifying lens and is water-resistant to 100 meters.
General reviews of the 126710BLNR emphasize its status as a highly versatile and comfortable luxury sports watch. The transition to the Jubilee bracelet is frequently praised for providing a more refined, dressy aesthetic compared to the Oyster bracelet version, while the upgraded movement is noted for its reliability and efficiency. Critics and enthusiasts alike highlight its exceptional build quality and strong market demand, though the high difficulty of obtaining the watch through authorized dealers is a common point of discussion in the watch community.
