I received this watch as a gift from a fellow Watch collector, usually high-end Swiss Chronographs. I can assure you this watch will not disappoint You in any way. I wanted to not like it as much as my other watches, just to be a watch snob. However I’m extremely pleased with this watch and am happily surprised at its quality. I really appreciate this gift and wouldn’t hesitate to get another for myself or as a gift for someone who appreciates a nice watch. For the price you really can not make a better choice in a time piece.
