Got it for 6.8k absolutely beautiful looks really good and is comfortable to wear.
Basic g shock features with a great design, I'd say its the best one after the carbon core series under 8k.
Go to casio's website to register the product It took me 18 hours for registration to be validated.
My product just had the watch nothing else, not even manual or a warranty card but the serial number would be engraved on back of your watch, I even called casio customer care to double check...
