    Comments about Ball Engineer Master II Diver Automatic Black Dial Mens Watch:

    Really like the look of the watch. Thought it might be a bit bulky for my wrist but I was mistaken.

    Very different from my other watches. Don't think I will ever dive with it... but love it for everyday use.
