For the last ten years or more I’ve worn a Casio Protrek Tough Solar 24/7. Tough. Excellent solar collection, never runs out. Mineral glass crystal has zero scratches still.
In the past I wore a Seiko Kinetic and wore out 3 stainless bands and three capacitors. Before that a G-Shock until the crystal was so beat up I could no longer see the display (and several resin bands). Before that a Timex Triathlon digital which also ended with a badly scratched up crystal.
This Protrek is maintenace free and totally reliable. The compass and thermometer are wonky but the barometer/altimeter has always been totally reliable. The time is fast by about a minute per year. The 3rd gen Tough Solar charged quickly and needs very little artificial or sun light to stay fully charged.
Large digits, good illumination, stop watch, laps, alarm, two time zones plus GMT. I have replaced the resin band twice and it has been snorkeling in salt water, swimming in chlorine pools, daily showers, yard work, physical labor, night shift, etc. Really the toughest, easiest to use, most reliable watch I’ve ever owned.
