Quick Take
So far, Watches & Wonders has brought us some genuine surprises, and not the least of them is the new SolarBeat movement-equipped Tank Must. The watch is the first solar-powered watch in the Tank collection, but it is also the first solar-powered watch ever from Cartier.
The watch is cased in stainless steel and comes in two sizes, at 33mm x 25.5mm for the large model, and 29.5 x 22mm for the small model. Cartier says that owners can expect, on average, a running time of 16 years before the watch requires a service (I assume that's the number of years that we can expect the rechargeable storage cell to last, as even rechargeable batteries have a finite number of recharge cycles). The idea is to not only make the watch an elegant, trouble-free, daily-wear, set-it-and-forget-it watch, but also to reduce its environmental impact, and in keeping with that theme, the straps – in black, blue, or light green – are made from non-animal leather, produced from scraps of apples grown for the food industry (in Switzerland, Italy, and Germany, says Cartier).
