24-hour chapter ring for DWX-D03

I have the Pepsi GMT dive watch. I would really like to replace the standard chapter ring with a 24-hour chapter ring similar to the Seiko SSK. Does anyone know of a somewhere that sells a compatible GMT chapter ring that’ll fit this watch?

Their new GMT expedition has such a chapter ring [MONTHLY DESIGN] GMT Expedition Kit | GMT Sports Watch with White FKM – DIYWATCH Club

Maybe email them and see if they sell it separately?
