I have been waiting with anticipation for this watch. Previously I have owned the original Hydroconquest in the past and, they are great watches but this new one is on another level. The green is absolutely stunning in the flesh, bezel action is crisp. The finish is up there with any watch and the bracelet is a revelation. The adjustment in the clasp is absolutely perfect. So far time keeping + 2 seconds. I would wholeheartedly recommend the Longines to anyone. The final thing is the diameter. I am used to wear 42mm Omega Seamasters and Speedmaster, the Hydroconquest wears very similarly and due to the super slim profile of the case fits comfortably under a shirt sleeve. Also, the lug to lug at approximately 51mm is comfortable. My wrist is approximately 7 inches for comparison.
