Query: invicta watch

I think the product is worthless. Too much image for a very bad quality product. On my 7th day using it, I accidentally dropped it from no more than 2 feet high, and it stopped working. I took it to a jeweler, and he said the "machine" was broken and it had to be changeg, more costly than what the watch cost me.
