Casio has made many different models of their Data Bank range of watches. Today's model is another of those, and one which seems they sold for very little money compared to what it does.
This model is a DB-37H (or DB37H), and is one of the Multilingual Data Bank models. It runs with a 2524 module and manages to get 10 years of life put of its CR2025 battery. Although this model first came out in the early 2000s, it still seems to be available today. Looking online, it is quoted as having a list price of around $25 which seems pretty cheap for what it does.
As this is a multilingual model, it can display in 13 languages (Eng, Por, Esp, Fra, Ned, Dan, Deu, Ita, Sve, Pol, Rom, Tur, Pyc), and the language choice suggests a world or european market model. The data bank mode is a 30 slot telememo, and it also has 5 alarms, a countdown timer, stopwatch, and dual time functions. Light it provided by a green LED behind the bottom corner of the display.
All the buttons for this watch are on the front, with 3 below the LCD display, and two more lower down on the case. The LCD display can show a lot of digits, with three lines of display. The middle and bottom line can show 7 and 8 digits respectively, and the top line is a dot matrix array.
This model has a Casio metal strap which has the part number S-928L. The case itself is plastic with a steel back plate, and the watch is 50m/5 bar water resistant.
