Since CLOCK, always absolutely precise time display. Since solar watch, in normal use throughout full battery. Functions such as displaying - Date (in the window at 3 clock) - Weekday (small dial at 6 clock) - 24-hour clock (in the subdial at 9 clock) - Radio reception (by pressing a button on a small dial at 6 clock) and - Battery power level (by pressing a button on a small dial at 12 clock); Further stopwatch (by pressing a button), and setting the world time (by pressing a button by turning the crown). Despite the various functions simple operation. Clock works by matt gold plating in connection with the brown dial and brown leather strap with the stable - very classy clip-lock - also frosted golden. Overall, not cheap, but good value.
