I have an Enzo EM001. Good watch. Weighs about 20lbs with the bracelet. Can be used to anchor a boat. The only problem is the bezel. Enzo is sending me a replacement bezel spring to improve the tension when they get in stock. Right now if I bump the bezel it moves. The case is very similar to the UTS. If you can pick one up in the $500 to $600 range it's a good value. His buffalo and leather straps are a nice quality and for me a good value.
I like the original Doxa's but never got myself around the new company. I don't see innovation, just re-issues of classics that are overpriced. The 5000 looses the traditional Doxa logo at 10 o'clock and starts to look like any other dive watch. The 750 is nice but I would prefer to hunt for a vintage piece.
