The Jacob & Co. Gotham City Black DLC Titanium (DC100.21.AB.AB.A) is a limited edition timepiece that pays homage to Batman and Bruce Wayne. Its 45.5mm round case is crafted from black DLC matte titanium, featuring a bat-shaped onyx dial with a yellow rim containing SuperLuminova. The watch is powered by the hand-wound Jacob & Co. JCFM10 movement, which includes twin flying triple-axis tourbillons at 5 and 7 o'clock, offering a 48-hour power reserve. The black rubber strap with a Condura pattern and black DLC matte titanium deployment clasp complete the striking design. This model is part of a limited series of 36 pieces.
