Abstract: The Belle~II measurements relying on the precise determination of the positions of displaced vertices are presented. It is the analysis of the $B^0-\bar{B}^0$ mixing and CP violation based on the early Belle~II data and the $D^0$ and $D^+$ lifetime measurement, where the world-leading accuracy was achieved already with the analysed data set. Lifetime measurements of other charm mesons are in the pipeline.
