Between those two; the spb. I have a Seiko solar chrono (a different model, but similar) and I love the watch, but it is a bit frustrating. The date window is terribly small and with the nature of solar watches, the date numeral(s) are set deep into the watch—difficult to read the date from a quick glance. With a bit more effort, the watch could have achieved a significantly higher degree of greatness. The power reserve indicator function is cool.
