For sale at Debonar Wacthes: pre-owned Rolex GMT Master II 126710BLNR "Batgirl" with original papers and box.It presents the caliber 3285 movement, which uses the Chronergy escapement and is regulated to an incredible +2/-2 seconds per day, and it comes on the Jubilee bracelet with the Oysterlock clasp. A bit of its story:While the Rolex GMT-Master has been around since 1954, the ‘Batman’ is the newest addition to the collection, featuring a now iconic black and blue ceramic bezel. It’s these bold colors, the same as the dark knight, that got it its beloved nickname after its release in 2013.When the Rolex Batman was released at Baselworld 2013, everyone took notice: it was the first of its kind. Rolex had already been using ceramic (aka Cerachrom) in their bezels for about ten years, but it wasn’t until the Batman GMT that they were able to use this tricky material to create a two-tone bezel.It's worth noting that the old Batman and the GMT-Master II with an all black bezel have both been discontinued. If you want a steel GMT it now has to be either the BLNR or the BLRO on a Jubilee.What about the "Batgirl" nickname?The nickname itself came from the fact that the lugs on the Rolex 126710BLNR are a bit thinner and more curved than the ones found on the original Batman GMT-Master II, plus the Jubilee bracelet provides the watch with a slightly more refined and dressy overall aesthetic.Note: the box in the photos is for picture use only, it's not included in the purchase.If you are interested in a Rolex box, contact us.
