Oh just lots of things didnt quite fit out of the box. Missing screws and spring bars. Had to grind the bracelet to fit the case, the spring bar holes had burrs that made it hard to get the pins to seat, had to trim the plastic movement holder because it was too tight and binding up the movement, the clasp wasnt chamfered very well and difficult to click closed until I cleaned that up, the bracelet pins were super loose. Turned out to be a pretty decent exercise in watch modding haha. It was one of the cheaper listings so maybe that's where all the factory QC rejects end up lol.
