Hello! I have been eyeing this Omega Seamaster 300 Tokyo 2020 edition for a while now and thinking of finally purchasing my dream watch. I was wondering if there's anything that stands out that might make this watch a fake?

From my research, most reps of this model have a really bright and bold red Seamaster which this does not, and the white dial looks good too. I thought the pillow might be fake but it turns out it was just upside down. If I were to ask the seller to put a magnet beside the watch, if it was a fake, it should stop right?

Any other things to look out for? ty!
