Stocker and Yale 650 and 660
The Stocker and Yale (SandY) P650 type 6 is standard issue to Army Rangers, Army Special Forces (the Green Berets), the Navy SEALs (Sea, Air, Land), and the multi-service EOD (Explosives Ordnance Demolition) teams. To date there have been three rounds of P650s: 1995, 1999, and 2000. All seem identical, save the date on the caseback and box.
The non-reflecting black reinforced-polyester injection-molded case is about 46 mm lug-to-lug, 45 mm wide, and 10 mm thick. Issued with a 20 mm black nylon wristband, it's designed for a 22 mm one.
