When I received this watch, it ran way too fast. I returned it easily to Amazon and ordered a replacement. The second watch works perfectly. This is a beautiful timepiece. It is my first Invicta, and I'm quite impressed with the look and feel of it. It is prominent in size without being overly large for my skinny wrists. The whole watch catches and reflects light - shines while I wear it. I've only had it for a couple weeks so I can't comment yet on the durability/reliability over time. So far, I find it to be a beautiful and very reasonably priced timepiece.
