More power, greater water resistance, and enhanced legibility
Each watch is powered by one of Seiko’s latest in-house automatic movements, Caliber 6R55, which has a power reserve of 72 hours. The watches are further enhanced to ensure water resistance to 300 meters, a first for Prospex non-saturation diver’s watches. The date window has been moved to the space between four and five o’clock to allow for a more symmetrical design and more space to be filled with Lumibrite, ensuring high legibility even in dark conditions.
