Casio CA-506-1 - Jared Leto - The Little Things
It looks like Jared Leto is wearing a Casio CA-506-1 watch in The Little Things (2021).
The watch is seen in this movie still from the trailer, where we can just see the white Casio logo. The shape of the case and band further identify this watch.
The Casio CA-506-1 calculator watch is not in production anymore but can still be found online for example on eBay (prices range from $25 - $65).
