>>2608467For me it has been the Casio WV-M120.
I've had it in use since 2011, it is solar powered, has water resistance of 10 Bars, can withstand first being in 90°C sauna and then ice hole swimming. Just an amazing timepiece. The wrist strap has been replaced few times during the years though. Also in Finland it doesn't get the amount of sun it needs during the winter. Also during army service it died a couple times during the winter warfare exercises due to coldness. (It was about -25°C ~ -30°C in those excercises, cellphones died out there too.)
