الوصف: We report the discovery of an S-shaped morphology of the radio galaxy J0644$+$1043 imaged with a 30 $\mu$Jy sensitive 525 MHz broadband (band 3 $+$ 4) uGMRT map. Dedicated spectroscopic observations of the host galaxy carried out with the 2-meter Rozhen telescope yielded a redshift of 0.0488, giving a projected linear size of the peculiar radio structure of over 0.7 Mpc. This giant radio galaxy is powered by a black hole of mass 4.1$^{+9.39}_{-2.87}\times 10^8$ \msun, from which vicinity emanate well-collimated and knotty jets, each $\sim$100 kpc long. The entire radio structure, presumably due to the effective jet precession, is less than 50 Myr old, has a power of $\sim$6 $\times 10^{24}$ W Hz$^{-1}$ at 1.4 GHz and the observed morphological characteristics do not strictly conform to the traditional FR I or FR II categories.
