With the field-proven Sureshot ballistic calculator, and traditional features: day, date, second time zone, alarm, chronograph (1/100th, lap time), countdown timer, and hourly chime. The Observer features a high-density poly-carbonate molded body, with an extendable strap to facilitate wearing the watch over a pair of wrist-length gloves. A bezel face can be adjusted to monitor your time. " "When you're using a long gun, it's essential to hit the target. As you start to go out to distances over 1000 yards, being able to hit that target becomes a science. The 5.11 H.R.T. Watch is a GREAT tool to help you dial in your dope, and make every shot count. Simply program in some numbers and push a button the watch does all the calculations for me. It is easy to use and makes my part of the job a breeze. I've used the watch for almost a year now with great success." Paul R. Basal III, GMC (SEAL/SS).
