The heart of the watch is a Meca-Quartz mechanism caliber Eterna 850, 22 jewels, Meca-quartz movements, were characterized by hybrid quartz and mechanical design.

Like the old mechanical chronographs, it is recommended that the reset is done as close to 0 as possible, because it operates at very high speeds, and the shock is very high, and the parts have a considerable age and can be fragile. The watch was serviced in March 2024, and it works within normal parameters.
