Editorial Product Review:Item Description:Nike produces only 1000 of this model each year. Designed in cooperation with four-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.
Amazon.com Item Description:Ride like the wind with the Nike Lance Armstrong 4 digital watch, which offers a number of powerful sport timing features and an easily readable display to keep you up to date on your progress as you race down the road. Additionally, it offers an accurate altimeter and it can track ascent and descent rates for total elevation gained or lost. A real-time digital compass updates your direction as you move. Nike's patented Zero Drift technology provides extremely accurate altitude information, eliminating barometric drift. Timing features include a 1000-hour chronograph with data recall, data recall, four time alarms, two altitude alarms, a hydration alarm, date display, and two time zones.
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.

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.

Awesome
I have had my watch for two years now and it is by far my favorite outdoor watch. I make regular use of all the features.
Compass: Once calibrated it is accurate, within 1 degree of my GPS. I used it exclusively to complete an all day orienteering event and numerous camping trips without complaint.
Altimeter: The altimeter, despite the proprietary "zero drift" technology, will drift over time, as all barometer-based alitimeters will. On a four day hiking trip in Colorado, I set the altimeter at a known elevation and it worked flawlessly for the whole trip. Based on map readings and GPS, the watch was never more than 200' off on a trip that regularly ranged from 10,000' to 14,000'. Another feature not mentioned in the manual is an alarm system that goes off whenever you attain an altitude of a famous mountain. For example, when I hit the altitude of Mt. Fuji, the alarm sounded and "Mt. Fuji" scrolled across the face. You will have to set the altimeter to a known point for it to be accurate. As a helicopter pilot I have flown numerous times with it and it is fairly accurate, but the sampling rate of 60 seconds is kind of slow - you can change it, but I don't seriously use it in the aircraft, and 60 seconds is plenty of time when you're hiking.
Temperature: Like any wrist mounted temperature sensor, the watch will react to your body temp. This watch has a feature that allows you to compensate for this by lowering the temp by a known factor. I have mine set at -8 degrees so it is relatively accurate on my wrist. This is the only watch I have found to have this.
Barometer: Accurately shows trend data - no complaints.
Alarms: I like having numerous alarms, and the alarm is sufficiently loud to hear while hiking in 30mph winds with the watch under layers of clothing.
The watch also has a feature to shut off the display after 1 hour of no button pushes. This saves battery power and my battery display shows a full charge after two years of consistent use.
The manual is not very clear, but the interface is user friendly once you play with it. The titanium bezel does show some wear, but the mineral face is as clear as the day I bought it and I am extremely hard on watches.
Overall, I am extremely pleased with this watch. I think I will buy a second one when the first one bites the dust.

A major disappointment from Nike
Before I bought this watch, I did a lot of research on the offerings from Suunto, Polar and Nike, and finally ended up choosing the Lance 4 watch for my cycling-specific activities. And I have to say, my disappointment began within 2 minutes of opening the shipping box. Here are the three major ways this watch (and Nike itself) have failed me:
1) This is a complicated, multi-function instrument. But if you're expecting a detailed instruction manual, forget it. What you get is an elaborate pictograph that illustrates which buttons to push. It skims over the setup procedure and many of the most important functions, and omits many features entirely.
2) Relative to the above complaint, I contacted Nike customer service about the setup. Since I'm a cyclist, I was particularly interested in the altimeter function, and dismayed by how thin the "manual" is. The instructions say you can select a 60-, 10- or 2-second sampling rate of the barometric pressure in order to determine altitude. What it fails to mention is what the ramifications are for choosing one over the other? Is one more accurate. Does one use more battery power? We'll apparently never know, because Nike's customer service failed to answer the question. While they admitted that they had received several complaints about the manual -- and were considering writing a new one -- they simply sidestepped my question about the altimeter function in their email reply.
3) And then there's the performance of the watch itself. In most cases it's impressive -- that is, in every case except the one for which I purchased it: the altimeter. On my group rides, there are always at least three other people with altimeters. A post-ride comparison of altimeter results always puts their readings within 3 percent of each other. The results from the Nike are at least 20 percent off. That means the altimeter results are not to be trusted.
While the watch is attractive (that's why it earned 2 stars instead of just one) and has an excellent band, it simply doesn't give me the accurate altimeter results I need. And since the altimeter results are so far off, I can only assume that its built-in weather sensor (also based on barometric pressure) is hugely flawed, too.
With the manual being as light on information as it is, with Nike's customer service either unwilling or unable to shed any light on the watch's usage and with the flawed performance of the altimeter function, I can only say that this watch represents a major disappointment. It may meet Nike's standards for fashion, but it fails my standards for performance.
