Functionality-wise: I want to hold on to the long battery life of regular watches. It doesn't need to last a year on a charge, but longer than a month would be nice.

In terms of style: a lot of the watches are designed to look expensive. I'm talking about things like glossy screens, fancy modern designs, and metallic bodies. These are things I want to avoid. I like the retro designs of the watches listed here[1], for example, with black, plastic bodies, and low-resolution screens.

Basically, I'm looking for a computer watch, which was the precursor to smartwatches. Is anything akin in that vein still being produced?
