they very smart, make it look smooth, but actually jump abit then move jump abit then move. my other 2 seiko watch, one $400+, one $800+ both smooth totally one.
the back is exactly this. its the exact same model. i saw some reviews in chinese also say the watch got problem. but no 1 realise its not automatic

Did a check and the brand uses largely Seagull and Hangzhou movements.
Not impossible that it stutters.. Just trying to figure out which movement could be inside to match the power reserve for you, but there are so many variations.
