The invicta men's 5728 is one of the most impressive watches I have ever seen. The shipping weight on this watch was 3.5 pounds. I own several invicta watches, but this one is by far the heaviest, most beautiful watch I have ever owned. When is comes to the technical description of a watch I will leave that to the nerds. I have lusted for this watch for six months or more. I discovered that if you see an invicta watch you would like to own, purchase it quickly if you have the funds. Once a dealer runs out of a certain invicta model it might not be available or even made again. In addition the limp wrist should not purchase the 5728 models. It's heavy!
