The Orient Kamasu RA-AA0C03S39B is a third-generation Kamasu diver featuring a clean silver-toned dial that gives the sport-watch silhouette a more versatile everyday character. Driven by Orient's Calibre F6922 automatic movement inside a 41.8mm stainless-steel case, it combines sapphire crystal with a unidirectional rotating bezel and 200m water resistance. Lume-coated hands and markers on a stainless-steel bracelet make it a practical yet stylish diving companion.
