OM factory was the first to mainly reproduce the Omega Speedmaster series, and the movement uses the 7750 to 9300 series movement. Among them, what watch friends are paying more attention to is Omega’s “Dark Side of the Moon”, which has a very good all-ceramic technology.

Later, the Omega Seamaster series, Audemars Piguet Royal Oak series, etc. were also launched one after another, mainly chronograph mechanical watches.
