I suppose a lot of men will love this Seiko. What's there not to like: A diver watch with a gunmetal  "black ice" luster, a strong lume, no need for battery, and the high quality of Seiko. The SKA427 on the gunmetal bracelet is a very manly watch. Though the bezel is supposed to be only 42mm across, this plays more like a 45 or 46mm on the wrist owing the large case that surrounds the bezel.

I love the big lume markers. After being charged about 75 percent, you only need to wear once a week or so to keep it running.

To know how charged it is, you wait for the second hand to reach the 12, then press the top right button. A full charge sends the second hand to the 6 position. Every time I press the button, the second hand goes to the 4, but that seems okay as my watch has been running since I owned it.

I love the build quality.

One thing that is exceptional is the movement of the bezel, very smooth, almost buttery.

I have several watches that are much larger, 52-55mm around the case, but the SKA427 is a substantial timepiece and in many ways is my perfect watch, appropriate for any occasion.

The Amazon photos don't do it justice so look at some pics I took of it.
