Description	A detailed analysis of new and existing photometric, spectroscopic and spatial distribution data of the eccentric binary V731 Cep was performed. Spectroscopic orbital elements of the system were obtained by means of cross-correlation technique. According to the solution of radial velocities with UBVRc and Ic light curves, V731 Cep consists of two main-sequence stars with masses M1 = 2.577 (0.098) Msolar, M2 = 2.017 (0.084) Msolar, radii R1 = 1.823 (0.030) Rsolar, R2 = 1.717 (0.025) Rsolar and temperatures Teff1 = 10700 (200) K, Teff2 = 9265 (220) K separated from each other by a = 23.27 (0.29) Rsolar in an orbit with inclination of 88.70 deg (0.03). Analysis of the O-C residuals yielded a rather long apsidal motion period of U = 10000 (2500) yr compared to the observational history of the system. The relativistic contribution to the observed rates of apsidal motion for V731 Cep is significant (76 per cent).
