We introduce our ongoing photometric and spectroscopic survey in the region of open clusters NGC 1907 and NGC 1912. The radial velocity dispersion of about 4 km/s in the clusters supports the interpretationj of physical interaction between them. We found 17 variable stars in the examined fields covering about 2/3 of the ``cluster area''. The relative low number (0.2%) of eclipsing variables supports the broadened internal velocity distribution to be the reason of the increased dispersion.
