The Technomarine Reef Black Chronograph GMT features a two-tone black and gold silicone case accented with stainless steel elements. It comes equipped with a matching black silicone strap. The unidirectional rotating bezel is constructed from scratch-resistant mineral crystal. This analog quartz chronograph boasts a black dial enhanced by gold tone hands and luminous markers for optimal readability in low light conditions. Index hour markers grace the face along with minute markers around the outer rim. A date display appears between four and five o'clock positions. The movement includes three sub-dials: one for 60 minutes, another for 60 seconds, and a third indicating the 24-hour chronograph time elapsed function. Additional functions include displaying two time zones (GMT) via a central second hand with varying hour/minute markers depending on position, standard hour and minute hands, along with a sweep second hand visible through a display window. The watch is powered by a VD53 quartz movement sourced from Japan. Water resistance reaches 200 meters / 660 feet making it suitable for diving activities.
