The watch itself looks original and pretty good - search online for "Raketa perpetual calendar" to see a host of examples like yours. However, the red star at top, hammer/sickle, and blue star on the second hand are not original and look stuck on - quite likely simply glued on to make a watch to appeal to a tourist market. You could remove them, but there might be some risk to the dial depending on the glue.
A bit funky, but a nice find! Welcome to the forum.
