The Cortebert 304 Chrono-Quartz movement, developed by Omega in-house, was one of the earliest hybrid (analog-digital) movements in the market. It consists of two distinct movements utilizing a single quartz resonator. The digital display offers timing and running seconds capabilities, while the analog display features minute and hour hand adjustments. The movement's name, "Albatros," is derived from the shape of its battery clamp. Notably, it was exclusively used in the 1976 Montreal Olympics Chrono-Quartz model. Key features include analog and digital displays and quartz precision.
