Here’s another sporty timepiece that relies on the unique Eco-Drive Japanese-quartz movement system, the Citizen Men’s Eco-Drive 180 WR100 Chronograph Watch. Featuring a stainless steel case and a black rubber strap, the watch gets its power from either natural sunlight or indoor light, so you never need to replace its battery. What’s more, it’s also water resistant down to 330 feet (100 M). $156.35.
