Just go for solar radio sync G-Shock square and you're done. No batteries, no setting up, extremely rugged and imo it looks good as well. Since I got that one a few years ago I only wear mechanical watch for various "occasions" - pretty much like a jewellery.

Look at moneybags over here paying $30 for a watch. /s

One thing I like about Casio's, especially the cheap ones, is how unpretentious they are.
