### ⭐⭐⭐⭐ has a timer
*by S***S on 18 April 2025*

Generally a nice watch with vintage vibes. Note that the B640 has a countdown timer which most other Casio models of the vintage range lack. I am not a fan of the strap and so I replaced it with a leather strap that had been adapted for Casio watches of these dimensions (e.g. the AE1200 is fitting the same kind of straps).
