It was sent off for authentication directly after purchase and sent back confirmed. Fingers crossed it won’t be a hard fix.That's worth fixing. Pre caliber 5 on the dial suggests this will have an eta 2824-2 which is a bonus since they are using sw200-1 now. Easy repair and easy to just replace the movement. This is assuming it is authentic, there were a lot of fakes on these. Opening the back will confirm authenticity so if you can do it safely and get a pic you can confirm the movement. But to be honest it looks legit.
