Casio absolutely dominates the calculator watch market, which is why they dominate this list as well. There are a few features that distinguish each of their models from one another, but they're all fairly similar in both appearance and functionality. You may see a wide variance in price, however, which is due to the fact that some of these units have been discontinued.
We included the Aeifond DZ09 because it has a useful calculator function while still being inexpensive; we figured that no one will pay an exorbitant sum for a smartwatch if all they want is a calculator. Many of the functions on the DZ09 can be glitchy, but the calculator is solid, so we recommend looking at all of the other features as simply an added bonus.
If you decide you like the extra gadgets, however, you may want to consider graduating to a full-fledged smartwatch. Expect to pay quite a bit more than you would for one of the Casios shown here, however, and don't expect to make nearly as much of a fashion statement.
