I bought this as the solar battery in my previous Promaster died, with the cost of repair impractical vs just buying a new watch. Beautiful watch, with all of the global time, atomic clock, and other timer, calender, etc... features one finds in a Promaster, along with the distinctive pilot's "whiz wheel" circular slide rule bezel. The only reason I downgraded from 5 stars was the lack of documentation, manuals etc..., that came with the watch, and related difficulty finding them online. My other complaint was the inadequate instructions for sizing the watch band. Also, once performing the sizing according to instructions, the watch band link pin does not stay securely holding the band links. I had to find a YouTube hack to remedy this.
This watch checks off all of my requirements. This included looks professional, larger diameter, easy to see at night, useful features such as world time and of course, perpetual time. My only challenge was figuring out how to initially set the time and date. Otherwise, I love the watch so much so I bought two different versions.
