This Luminox Men's 3007 Original Navy SEAL Dive Watch arrived quicker than expected and is exactly as advertised. I'm not sure how Luminox describes its models, but I had a Luminox Men's 3051 EVO Navy SEAL Colormark Watch previously that I understood was the genuine Navy Seals dive watch. Perhaps the 3007 is the **original** version. The 3051 is a bit bigger, better looking (in my opinion) but a bit more expensive. While the 3007 is a good watch, well built, accurate, waterproof and attractive, I think I'd choose to spend a few dollars more to get the 3051 now that I've seen them both in the flesh.
