Let me say from the start of this review thet this is a great watch. I have just returned from diving in the Dominican Republic and  did not intend to use this watch for the deep dives I had planned. I was wearing the watch because I just like the the nice burnt orange color of the bezel ring. I normally dive with watches that are well over rated for the depth I dive such as the Deep Blue Pro Tac Diver 1K or the Victorinox Black Ice rated to 500 meters. But on one particular two tank dive last week I left the dock headed out to dive a wreck sitting at a depth of over 150 feet wearing the Momentum watch. At this point I should state that I am a NAUI certified Master diver and a certified cave and overhead diver with several hundred dives as such. So it goes without saying if you are not certified beyond recreational diving please stay within your training level. On with the story... So I made the decision to take the Momentum down to the wreck with me. I use a Sherwood Wisdom intergrated dive computer so I knew if the watch failed me at depth I could count on my computer for a safe dive. At an average depth of 130 feet for 25 minutes on a repetitive dive chart I was very pleased that the Momentum M1 Deep 6 stayed tight and sealed! So there it is... A nice looking watch that out performs it's price range. The time piece is accurate. And the bezel ring is snug and does not "drift" forward while wearing it. I personally changed one thing about the watch and that is I put a fast wrap strap on the case. Nothing really against the factory strap I just prefer the comfort of fast wrap straps. This watch is also easy to read above and below the surface and maintains the illumines glow through the night! Just note that only the hour and minute hands along with luminus dot on the bezel ring remain bright enough to see through the night. I believe this a good time piece for the money and would highly recommend it to my friends.
