I Bought Casio G-SHOCK G-9200 from Watchkart, it got delivered in time. I found some issues so I directly called Casio India no they said you warranty card should be signed & stamped by company you purchase otherwise Casio not considered it as warranty.
WatchKart give only invoice but not the warranty card stamped. not it seems product has something fake into it without warranty.
Moreover, WatchKArt contact nos are not available to call. Anyone buying, please call casio before buying them.
