students writes: For about 20 years I have used Casio Databank 150 watches. They were handy because they kept track of my schedule and the current time. They were very cheap. They require very little maintenance, since the battery lasts more than a year and the bands last even longer. Since they were waterproof, I do not even have to take them off (or remember where I put them!). They were completely immune to malicious software, surveillance, and advertising. However, their waterproof gaskets have worn out so they no longer work for me. Casio no longer makes them or any comparable product (their website is out of date). I don't want a watch that duplicates the function of my cell phone or computer. What is the best choice now?
