44mm gents Citizen Watch. For avid marine sportsmen who value style as much as function, Citizen’s Promaster Sailhawk with Eco-Drive technology is the perfect combination of the two. With a blue polyurethane strap and numbering detail, offset with a stainless steel case, black aluminum bezel and dial, this watch isn’t blending into the background. And with features such as a yacht racing timer, a 99-minute countdown timer, two separate alarms, split lap times, the ability to show the time in 30 cities worldwide, and water resistance up to 200 meters, there is no water-based activity this timepiece can’t handle with ease. Never requires a battery.
