LL Cool J wears a Suunto X-Lander Military, as special agent Sam Hanna in the NCIS: Los Angeles television series. The watch can be spotted on the promotional image and for example in Ambush (Episode 8 of Season 1), when Sam Hanna uses his watch to send morse code using the reflection of a laser beam.

The X-Lander watch from Suunto is a real outdoor instrument featuring an altimeter, barometer, compass and most common watch functions (3 daily alarms, calender, stopwatch with split time and a countdown timer), in a tough metal case. X-Lander Military variant, as used by LL Cool J, features black aluminum casing and a black rubber strap. Other model variations with different colored cases exist as well.

Get it for the best price at Amazon.com ($281.15). Make sure you get the all black "Military" model if you want to get the same version as LL Cool J.
