I bought a watch from aliexpress.com I came 2 weeks late and it was broke I am a watch collector and seen the flywheel was bad I emailed the seller and he said lol and the rest was in Chinese I took it too my jeweler who I know for many years who was a close friend and she said the flywheel is broke I took pictures and video and sent it to aliexpress.com and they said there is nothing they can do even though they have a 30 day return policy I paid $117.00 for the watch and they did nothing.
