Pretty much my only watch now is a Casio G-Shock Tough Solar. My criteria for a watch is it needed to be "self-sufficient", i.e. self-winding, kinetic quartz, etc. (so the battery doesn't die at an inopportune time), as well as tough (I only take it off to lift weights), waterproof (at lease 150m), and be accurate/stopwatch (for running). I had Seiko mechanicals for many years, but missed the features on an LCD. The G-shock solar pretty much has everything (except the dressy look of Seiko's), and was less than $75.
