Product Description:
Nike produces only 1000 of this model each year. Designed in cooperation with seven-time Tour de France winner Lance Armstrong. Engraved and paint-filled Lance signature on backplate. Altimeter with Zero Drift Technology uses a special algorithm that determines whether a barometric pressure change is caused by altitude change or a weather system, letting you accurately track your ascent-descent rate, current altitude, maximum altitude, and accumulated altitude. Weather Mode utilizes an accurate barometer that measures atmospheric pressurethe best indicator of changing weather conditions. Real-time digital compass always points north, while your current heading is displayed, includes a level bubble for even greater accuracy. Dual-layer display for Compass and Timer vastly enhances the readability of crucial information, including compass north heading, and graphic countdown timer showing time remaining. Solid Titanium case utilizes one of the lightest and toughest metals available on the planet. 1000-hour chronograph enough for a month-long race. Seven extra-loud alarms for time, altitude and hydration--to remind you when to drink and eat to maintain your energy during a race. One-piece, pinless strap construction utilizes the watch body as an integral part of the strap rather than using fragile pins, making it nearly impossible to break the watch free of the strap. Strap Keeper eliminates the flapping strap problempermanently. Battery hatch on backplate provides quick and easy battery replacement. 100m water resistance. Two year manufacturers warranty.

The solid titanium case has cross-cut metal buttons that improve button actuation even with gloves. A pinless screw back construction screws the watch to the strap for durability and a strap-keeper post locks down the strap to prevent flapping. Other features include water resistance to 100 meters (330 feet) and a scratch-resistant mineral glass crystal. It's also individually numbered watch with Lance Armstrong autograph etched on it.

Rating : - I was stupid enough to by a second when the first failed.
I agree with other reviews, that this is a difficult piece to master. The altitude dirfts from -150 to +250 feet per day. I live at 5005 feet in elivation and have to set the watch at least once a day to keep it accurate. The temperature function is always off. The compas seems to work well. All of this is nothing compared to the time when it became necessary to replace the battery (less than one year with both watches). I didn't have the necessary special tools to replace the battery. Replacing the battery was a major accomplishment. I could not get the first watch to work after replacing the battery. The second watch quit working when the factory battery failed and I finally threw it away, as I had done with the first one. If you want to buy a watch that will work for the life of the factory battery only, this is the one for you.
