The Casio G-Shock GA-100B-4AER is a shock-resistant resin watch built for rough use. It combines analog hands with a digital display and adds a 1/1000-second stopwatch with speed, distance and Mach readouts, plus a 24-hour countdown timer. It is water resistant to 200 meters and weighs about 70 g on a 55 mm case. Against slimmer G-Shock models it is bulkier but offers more measurement tools; against smartwatches it gives up notifications and GPS but needs no charging.
