Three hundred years ago, John Harrison’s chronometer changed everything, making long-distance sea travel safer by solving the mystery of longitude. Today’s GPS sailing watches are direct descendants of that breakthrough—only now, they stream live data to your wrist.
From tide tracking and MOB alerts to autopilot integration and storm warnings, these wearables are essential for anyone serious about life under sail. With models ranging from under £100 ($120) to luxury tech costing more than a used yacht, there’s a perfect fit for every skipper. We’ve handpicked the smartest sailing watches of 2025 to help you chart your next course with confidence.
