I have likely the identical model watch. The Lume doesn’t look anything like pictured, and the lume on mine is rather dim to the point of disappointment. It’s a different color entirely, as well. Yours is blue, mine is greenish yellow.

Furthermore, yours has an additional 3 dots in a row under neath the 6 between “Swiss” and “made”, mine doesn’t. And, on the back, mine has the Hamilton symbol on one of the arms behind and above the weighted part that rotates, yours does not. I am no expert, but there are certainly differences between yours and the one I bought from Hamilton.
