I purchased the WD1680Q dive watch
I purchased the WD1680Q dive watch on Amazon and it's a beautiful watch with excellent features for a fraction of the price of other watches. I also bought the OTF clasp direct from Watchdives. At first I could not install the clasp myself. I thought the included parts were the wrong ones. I emailed their customer service over the weekend and by Monday i had a response. By then I figured out that the include parts were the correct ones and I very easily swapped out the clasp. The person who responded was very kind and understanding.
