The utility model relates to a high-accuracy magnetic damping automatic leveling instrument, which comprises an instrument body; an eyepiece assembly, a reticle assembly, an auxiliary lens assembly, a focusing lens assembly and an objective assembly are coaxially and sequentially mounted inside the level body from right to left, wherein the a magnetic damping compensator assembly is arranged between the reticle assembly and the auxiliary lens assembly. The utility model has the benefits that while being provided with a high-accuracy magnetic damping automatic leveling compensator, a product can obtain the horizontal sight line; and as exact leveling is not required, the observation time in leveling can be shortened, and micro inclination of the sight line caused by micro vibration of the ground of a construction plant, instrument subsidence on a yielding ground, big wind blowing and the like can be quickly leveled. Therefore, the utility model has the advantages that the observation accuracy during leveling i
