N2 - The results are given of detailed surface B, V, and R(c) photometry of IC 1689 - a galaxy with an inner polar ring. It is shown that the central galaxy is a normal SO-type galaxy with a relatively short and warped stellar disk. The inner polar ring (its radius is only about 2 kpc) has blue colour (B - V = +0.3, V - R(c) = +0.3) and comparatively high surface brightness (mu(B) approximate to 23.2).Comparison of observed surface brightnesses and colours B - V for all single polar rings studied earlier show that there is a dependence between these characteristics. We interpret this dependence as a consequence of the fact that global bursts of star formation may occur (with a burst strength up to 0.15) in many polar rings in the course of their evolution.
