Seiko 5 Automatic model with a striking dark blue "crosshair" dial. Reference number 6119-8060T means that watch uses the Seiko 6119 caliber, a robust automatic movement known for its durability. It features 21 jewels. This particular reference number (8060) is historically significant because a very similar model (the 6619-8060) was famously used by MACV-SOG covert operations teams during the Vietnam War. While this 6119 is a later civilian version, it carries the same "8060" reference lineage that is highly respected by vintage Seiko collectors.
