This OMEGA Seamaster Diver 300M GMT Chronograph features a matte blue dial with 30-minute and 12-hour recorders and a small seconds sub-dial. There is a yellow GMT hand that matches the yellow 24-hour scale on the dial which makes it possible to keep track of time in a second time zone. The matte blue ceramic unidirectional rotating bezel is mounted on a 44 mm stainless steel case with a helium-escape valve. The watch is presented on a stainless steel bracelet. This chronograph is powered by the OMEGA Co-Axial calibre 3603.
