Not to be a Debbie downer but that is supposed to be the bezel off a 2500 movement planet ocean but it is not legit IMO from the picture given. The pip placement is way off. (No offense intended to whoever made this if they were upfront about using replica parts)
Its an aftermarket bezel. An homage to the PO not an exact replica from what I remember. Modding is not intended to copy 100% the watches it takes cues from but to mix some of those parts together to make something unique and usually affordable. No offence taken as I didn't want a replica.
