I'm not an expert, but I compared this listing with another listing from a genuine watch, that also has a bezel protector. I think the OP is right. This listing looks "off." From OPs' listing, the "20" and "50" look too thin, and the date looks off. If you have two tabs open, one with OPs listing and one with the other listing, it really looks noticeable.
