Omega 286 Description
The Omega 286 is the final evolution of the celebrated 30mm manual-wind, sweep-seconds movement family that began with the 30T2 SC. Produced from 1961-1966, this robust and highly reliable caliber is famously associated with the Omega “Seamaster 30” models, where the “30” proudly references the movement’s diameter. It represents the culmination of over 20 years of refinement on a legendary and accurate workhorse design.
