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.

Features

Sandy P660 prototype

• 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.
• The P650 is labelled as water- and shock-resistant
• A sapphire glass covers the watch.
• Dial is high-contrast white lettering on a matte black background. Standard 12-hour markings with 24-hour annotation. The distinctive radioactive tri-foil symbol appears on the watch face as does the H3 (Tritium) notation.
• The hour positions, the zero position on the unidirectional bezel, and the hour and minute hands each have a brightly-glowing vial of tritium gas. Taken together they contain less than the personal limit of 25 millicuries. (U. S. Nuclear Regulatory Commission regulations 10 CFR 30.15.)

Stocker and Yale made only a small number of P650s above their contractual requirements for the government. This surplus must be exported from the USA, per licensing agreements. Several civilian variants of the P650 are seen such as Traser and Luminox.
