The black triple-register dial features luminous hour markers and hands, with a small seconds subdial at 9 o’clock, ensuring optimal legibility. The whole is protected by a Plexiglas crystal, faithful to the original aesthetic. The watch is fitted with a stainless steel bracelet with an Omega concealed folding clasp.
