Novelty watch maker Jerome Romain unveiled a new Batman-themed watch last Monday, according to the FT (paywall). The Batman symbol glows blue in the dark and the watch’s crystal sapphire back features a map of the Dark Knight’s beloved Gotham City. The must-have for geeks will cost you a steep USD 19,400. It’s not the first time a high-end watch brand takes a punt at the Dark Knight, with Jaeger LeCoultre making an edition in 2012 that was actually worn by Christian Bale in the Dark Knight Rises.
