The latest XO Submarine collection embodies the sporty yet classic art form that makes GV2 a standout. At the intersection of design and technology, the automatic XO Submarine announces state-of-the-art geometric design that pays tribute to its namesake. Dating back to a time when watches graced the walls of battle's submarines, the XO Submarine features a unique square case surrounding the circular dial with gear-like dual time zones and a rotating inner ring. Water resistant to 100 meters, the XO Submarine is perfect for timing those deep dives. In bold, dark colors with luminescent hands and hour-markers, this sleek collection is ideal for special strength surgeries or hard-working everyday wear.
