Does it not have an automatic movement? Because the idea is pretty lame if it does.

I’ve had this a couple of times and always got my money in the end. As you stated the seller has no obligation to accept a return.

I always make clear photos and a video of all working functions with a time stamp before sending the watch, just to prevent these arguments. And state that the watch is fully functional but might need a service, if it’s been a long time ago.

I would contact chrono, if not already, and explain that the watch is as described and you’re not willing to accept a return.

Gran sport models are automatic. I’m sure there are a couple more besides those, Squadra as well.
