Was going through Aliexpress for a bit and came across this. Seems like a pretty good alternative to the classic Casio watches (https://www.amazon.com/Casio-Classic-Digital-Watch-Color/dp/…)
Update: These aren't stainless steel but are chrome painted plastic.
Cheap ~$2 watches have been around for decades. Not similar to a Casio, so not an alternative IMO.
