Gotta love the "Radiation Logo"...heheh.
All have the "Stop Second hack movement (movement stops when stem is pulled out)" so you can sync watches as needed.
They are also all lit with Tritium, so approx 12 years of "glow in the dark"...heh.
You can only buy "sanitized" versions publically, but if you search around (especially eBay), you can buy the Official Gov. Issue with NSN (Nato Standard Number) on the back. Typically run from $100-$200 on eBay depending on your luck.
There is also a guy here that sells them, but some of them look like sanitized versions (no Gov. Issue logo etc):
