Should be fine. It's listed under Marco's retail: https://www.marco-groups.com/our-products/s...nd=3&category=1
I think most importantly is you need to check/ make sure got warranty card and it's issued by Marco Corp, the authorised distributor of Casio.
I would not risk buying from those online shops. There's a lot of uncertainty about their warranty and the source of their products. If you prefer online, Marco also have an online store in Lazada but I think the range of products is smaller. Not sure if you'll find the watch you want. Most of the time I usually prefer to buy from the retail shop, I feel better having touched and checked the product before purchasing.

And I saw this on their FB: https://www.facebook.com/CasioTimepieceMala...?type=3&theater

Something should be happening tomorrow maybe can watch out for some deals or whatnot.
Hahahahahaha what were you looking for?

Hahahahaha goodness
Manufacturer warranty? Isn't that fishy? Casio don't have service centre in Malaysia, it's all under marco. Where is this "manufacturer warranty"? Better check before making your purchase.
