The center of the dial stays a fairly consistent nice blue color, but the indices are where this watch really shines. The indices are designed in such a way that when light hits them they light up in almost a bright jewel tone blue. You have to see it in person, but you can sort of get an idea at just shy of the 1 and 7 hour markers. While the bracelet of a Royal Oak may look a little better, I’d definitely take this watch over a comparable blue/steel Royal Oak chronograph. The quick change bracelet/strap system is nice and Vacheron provides you with not only the bracelet, but a matching leather strap as well as a rubber one. Lots of versatility with this Overseas, and the blue dial really makes the watch.
