Like the open escapement. Would like the hands to be darker Hard to read in low light. Do the hands have fluorescent paint? I really wanted an all blue face but that option-was not shown initially. . I did not like the black trim on the only blue face shown. Also the watch size is a bit large . Size of the face info should be more prominent. Note: I was given an eye shaped Hamilton watch for graduation in 1963. I rarely wear it. But now ibelieve it is very collectible.. also who needs quartz changing batteries. I saw this current watch on a friend and really liked it. It had a red face. I also liked that it is self winding. The style and price point appealed to me. Historically I knew that Hamilton was a quality reliable brand in watches.
