I have only used this watch for two weeks so I can not comment yet of its durability. The only reason I give it only four stars instead of five is that the wrist band is too small for men with large wrists. I had to stretch it on a bottle for awhile before it was comfortable enough to wear. I could have made another hole in the band but decided against it as it might void the warranty. Other than that problem this watch appears to be tough and most likely will hold up under my harsh working conditions. I doubt I will use all its features but important to me the basic functions keep working and that it keeps the correct time. I will give an update in the future but for now I am glad I purchased this watch and the price and free shipping were a big plus too thanks to Amazon.
