Abstract: We present our multicolour photometric data of the primary and secondaryeclipses of OW Gem that took place in 1995, 2002, and 2006, as well as the newradial-velocity data collected since 1993 by R. F. Griffin and A. Duquennoy.The Wilson-Devinney code was used for the simultaneous solution of bothphotometric and spectroscopic data. A complete set of orbital and physicalparameters of the components was obtained. The pair of values, eccentricitye=0.5286 and argument of periastron omega=140.73 degree, give bettercompatibility of the moment of the secondary minimum with the observationscompared to previous estimates.
