・ The Black Series Limited Edition A design concept that focuses on the visibility unique to PROSPEX, which reduces stress on the wearer by keeping the appearance the same in bright and dark places.
-Adopting the newly developed "Green Lumibright Pro" We have developed a green Lumibright with higher brightness and longer afterglow time than normal colored Lumibright. It emits light in green, which is the most perceptible in the dark, and improves visibility in the dark.
-Image of the scene seen from the night-vision scope The appearance of the green Lumibright shining in the all-black case expresses the scene as if looking through the night-vision scope. A new design style not found in the previous The Black Series has been realized.
-SBDY121: A field watch derived from a diver's model commonly known as the turtle, which features a rounded classic design. Uses a fabric strap that is easy to incorporate into off-scene styles.
