You won't find a screen dominating the front of the Alpina Seastrong Horological Smartwatch, but that doesn't mean it's limited to telling time. Indeed, thanks to its connected movement developed in collaboration with MMT, it can track your activity, relay notifications, and automatically set the time just like a computerized watch. But it's also still a real Swiss diver, with a uni-directional rotating bezel, sporty 44mm fiberglass case, and a water resistance rating of 330 feet. Available in four models, which mix black or blue dials with black, green, orange, or navy bezels, finished with rubber straps.
With 23 different complications primarily devoted to the study of the night sky, the Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication Watch is one of the world's most complex timepieces. On the front, it offers traditional time indications, a perpetual calenday, a precise moon phase, solar time indications, and a tide-level indicator with a 3D depiction of the alignment of the Earth, Moon, and the Sun. The back dial is dedicated to a transparent celestial chart, which lets you admire the inner workings of the watch while observing celestial time in both hours and minutes. It's housed in a 45mm 18K white gold case, finished with a black alligator leather strap, and is one-of-a-kind.
