A great everyday companion.
Overall this is a great watch for the price. Swiss Made and the right size for a larger dial vs. others in the class. The dial color is more gray than black which was a plus for me as I was looking for a gray dial. I switched out the band for a black field band bought on Hamilton’s website. I am very happy with the results!

The Perfect Everyday Watch
This hands down is the best everyday watch. I have a large wrist so the 42mm works perfectly for me. The all brushed titanium looks great. The subdued look and clear dial just only make it better. I didnt want to believe the Hamilton hype but I have to say that Hamilton makes a great solid watch. If you are looking for the everyday watch that just feels right, is solid, and works, look no further. I am sure the standard version is just as good also. ALSO, the dial is not black black. It is slightly a grayish tone. At first I hated this detail but after looking at it, it just looks so good.

Hamilton titanium is worse than mediocre
Where can I start with how bad this watch is? (1) the movement is a derated movement with a low beat rate. This means the seconds hand visibly clicks almost like a quartz watch. (2) the beautiful dial is rarely seen because there is no anti-reflective coating. Instead, you see overhead lighting when you check your watch. (3) the watch is already oversized, but the excessive lug-to-lug length makes this look like a clown watch. Make sure your wrist is 8" or more for this watch. (4) it's dainty for a field watch. The push-down crown easily pops out, making rain or sweat a real watch killer. It's also gets scratched at the slightest touch. (5) the superluminova on the hands and face is so thin that it is worthless. (6) When I say Seiko and Timex make better automatic watches, I don't mean "better value" or "better for the money." I mean that Seiko and Timex have better movements, better styling, better wearability, better durabity, better visability... all around better. The Hamiltons released with the low-beat H-10 are bringing shame to the one-respected Hamilton brand.
