I love watches. I could talk all day about them. Since we're taking about gadgets, I think it's only deserving to bring up F.P. Journe's Sonneire Souveraine. For about $650,000, you can get yourself one of the most insanely complicated watches on the market. Aside from telling time, inside this watch you have a minute repeater, a grand Sonneire, and a petit sonneire. Basically what these complications do is tell the time by chiming, which may sound simple since your Casio can do it, but this watch is entirely mechanical. No batteries. The sonneire is like a continuous alarm, the grand sonneire chimes every quarter hour telling you the hour and the quarters into the hour, and the petit sonneire just chimes every quarter hour telling you only the quarters, not the hours. These can be turned off and on. The minute repeater uses these chimes to tell you the exact time when activated. In particular, these complications are so difficult to achieve because it takes a lot of energy to continuously reposition the gongs that strike to make a chime noise. As this is a completely mechanical movement, this sort of energy displacement is no easy feat. Off the top of my head, I can only think of 4 other watchmakers that have made a watch with a sonneire. It's an engineering marvel, of high horological significance and elegance. A grail watch for sure.
