Probably the cheapest Casio watch you can purchase brand spanking new from any high street or online retailer at the present time, the MQ-24 is one of the most popular and simplest Casio timepieces ever made.
With no date complication, no lume, no water resistance worth mentioning, an acrylic crystal, and really quite small at only 34mm in diameter, you'd be forgiven for wondering why something like this is still being made at all. You could ask the same about any watch really though, especially these cheap plastic ones.
Truth be told, not everyone needs anything more from a watch other than to tell the time, and if that is your only concern, why spend a fortune on one? Bank clerks, students, shop workers, children, popstars, celebrity actors, fashion-conscious young women, and even the Pope wears one of these Casios, and if it's good enough for that wide-demographic, it's good enough for anyone.
One of the things to look out for is the clip-on backplate on these Casios because there are many fakes out there with an F-91W style caseback with the 4 little screws (one in each corner) which is a dead giveaway. Yes, they even fake these watches now, and of course, Skmei do their own version named the Skmei 1419 which is a 1:1 clone as well.
One of the major drawbacks is the plastic buckle on these watches which will break if given rough treatment. I know because I also had to buy a new strap, but the straps are cheap as chips anyway. It's awkward that the 16mm lug size means you can't just use an 18mm F-91W strap unless you trim the edges, but it can be done.
On my 7.25 inch wrist, there aren't many holes left, but is slightly longer than the one on the Swatch Once Again (the other Pope watch), and typical with Casio hole placement, the strap is either a bit looser than I'd like or a bit tight (although it's more of an optical "fat squeezing" thing rather than actually feeling tight).
Overall, the Casio MQ-24 is a good basic watch. It's very legible, and with the white dial really being the same size as a dive watch without the bezel, it's not stupidly small. The seconds hand on mine hits every marker exactly too, but it may not always be the case with these cheap Miyota movements.
There are a few different variations with number sizes and colours, and there are bigger models such as the MW-59 (40mm with date) or the MW-240 (42mm), but if I were to get another one, I'd probably go the Skmei route because they have even more styles to offer for a lot less money. Skmei also don't charge you double or triple depending on the most popular colours unlike Casio.
