This is an excellent. It's CRAZY accurate and easy to operate. The fact that you can precisely adjust (re-register) the positions of the various hands is important. The bracelet is exceptional -- beautiful, strong, and easy on and off. This is a BIG (45mm) and relatively heavy watch, although it wears easily on my 7" wrist. It's comfortable. My only complaint is the legibility of the hour hand when it is positioned over one of the three registers -- it's hard to quickly see. The color of the frame of the hour and minute hands is the same as the circumference of the registries -- satin silver. This is a design flaw. Also, because the frame of the hour and minute hands is thick, the lume material is narrow, which provides a minimal luminosity of those hands at night. The lume is acceptable, but -- compared to typical Citizen and other Seiko models -- it is marginal. Nevertheless, it's a keeper. I like it.
